Ratio 3 raises it to about 45.45 ms and is better treated as a temporary response to instability. It can cover an occasional gap.

Typing a larger number into the console doesn&#8217;t make a standard server run more simulation steps or send more snapshots.<\/p>\n\n\n\n<p>Current <a href=\"https:\/\/docs.comfig.app\/latest\/customization\/modules\/\">mastercomfig documentation<\/a> makes the same distinction. Its standard packet-rate option uses 66. A rate of 100 is available for custom boosted-tick servers, not as a baseline for Casual or an ordinary community server.<\/p>\n\n\n\n<div class=\"ti-interp__table-wrap\">\n<div class=\"table-wrapper\"><table>\n<thead>\n<tr>\n<th>Connection<\/th>\n<th>Ratio<\/th>\n<th>Buffer at 66<\/th>\n<th>Use<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Typical or unknown<\/td>\n<td><code>2<\/code><\/td>\n<td>30.30 ms<\/td>\n<td>Safe start<\/td>\n<\/tr>\n<tr>\n<td>Clean and steady<\/td>\n<td><code>1<\/code><\/td>\n<td>15.15 ms<\/td>\n<td>Lower buffer<\/td>\n<\/tr>\n<tr>\n<td>Mild jitter<\/td>\n<td><code>2<\/code><\/td>\n<td>30.30 ms<\/td>\n<td>Extra interval<\/td>\n<\/tr>\n<tr>\n<td>Unstable<\/td>\n<td><code>3<\/code><\/td>\n<td>45.45 ms<\/td>\n<td>Temporary<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n\n\n\n<p>Ratio 2 is the sensible recommendation when the player&#8217;s route is unknown.

It sends snapshots containing updated game states. Without smoothing, the player model would step from one received position to the next.<\/p>\n\n\n\n<p>Interpolation fills the space between those known states. TF2 holds a short snapshot history and renders remote entities slightly behind the newest information it has received.<\/p>\n\n\n\n<div class=\"ti-interp__timeline\">\n<div class=\"ti-interp__tick\"><strong>Server tick<\/strong>The authoritative match moves forward.<\/div>\n<div class=\"ti-interp__tick\"><strong>Snapshot<\/strong>Updated entity states travel to the client.<\/div>\n<div class=\"ti-interp__tick\"><strong>Buffer<\/strong>Recent known states are held briefly.<\/div>\n<div class=\"ti-interp__tick\"><strong>Display<\/strong>Remote movement is drawn between them.<\/div>\n<\/div>\n\n\n\n<p>The remote Scout on your monitor is a smooth reconstruction of states the server has already sent, not an exact picture of the server&#8217;s current instant. It isn&#8217;t a future position, either.<\/p>\n\n\n\n<p>Source uses prediction for your own movement so input doesn&#8217;t wait for a full trip to the server and back. Prediction makes local input feel responsive. Interpolation smooths received remote states.<\/p>\n\n\n\n<p>The server remains authoritative. It controls movement, collision, weapon timing, damage, healing and projectile simulation. For attacks where lag compensation applies, the server can evaluate historical player positions associated with the attacker&#8217;s command time. The <a href=\"https:\/\/developer.valvesoftware.com\/wiki\/Source_Multiplayer_Networking\">Source multiplayer networking documentation<\/a> explains that the server knows the client&#8217;s interpolation amount and includes it in that process.<\/p>\n\n\n\n<div class=\"ti-interp__warning\"><strong>That isn&#8217;t a client-side hit override.<\/strong> Lag compensation doesn&#8217;t give the attacker authority over the match, rewind every world object or drag a projectile toward an earlier player position.<\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/tradeit.gg\/blog\/wp-content\/uploads\/2026\/07\/tf2-interpolation-timeline.webp\" alt=\"How TF2 interpolation and lerp work\"\/><figcaption class=\"wp-element-caption\">How TF2 interpolation and lerp work<\/figcaption><\/figure>\n\n\n\n<h2 id='cl-interp-and-cl-interp-ratio'  id=\"boomdevs_3\" class=\"wp-block-heading\"><code>cl_interp<\/code> and <code>cl_interp_ratio<\/code><\/h2>\n\n\n\n<p><code>cl_interp<\/code> supplies an explicit interval in seconds. The ratio creates another interval from the accepted updaterate. TF2 uses whichever result is larger:<\/p>\n\n\n\n<div class=\"ti-interp__code\">effective interpolation =\nmax(cl_interp, cl_interp_ratio \/ cl_updaterate)<\/div>\n\n\n\n<p>If you set <code>cl_interp<\/code> to zero, the ratio calculation still happens. For example, at an update rate of 66:<\/p>\n\n\n\n<div class=\"ti-interp__table-wrap\">\n<div class=\"table-wrapper\"><table>\n<thead>\n<tr>\n<th>Configuration<\/th>\n<th>Calculation<\/th>\n<th>Result<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><code>cl_interp 0<\/code>, ratio 1<\/td>\n<td><code>1 \/ 66<\/code><\/td>\n<td>15.15 ms<\/td>\n<\/tr>\n<tr>\n<td><code>cl_interp 0<\/code>, ratio 2<\/td>\n<td><code>2 \/ 66<\/code><\/td>\n<td>30.30 ms<\/td>\n<\/tr>\n<tr>\n<td><code>cl_interp 0<\/code>, ratio 3<\/td>\n<td><code>3 \/ 66<\/code><\/td>\n<td>45.45 ms<\/td>\n<\/tr>\n<tr>\n<td><code>cl_interp 0.05<\/code>, ratio 2<\/td>\n<td><code>max(0.05, 2 \/ 66)<\/code><\/td>\n<td>50 ms<\/td>\n<\/tr>\n<tr>\n<td><code>cl_interp 0.1<\/code>, ratio 2<\/td>\n<td><code>max(0.1, 2 \/ 66)<\/code><\/td>\n<td>100 ms<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n\n\n\n<p>Once <code>cl_interp<\/code> is larger than the ratio result, it becomes the floor. Remote entities are displayed farther behind the newest received state. It doesn&#8217;t move your character ahead, make you harder to hit or let a weapon attack sooner.<\/p>\n\n<h2 id='what-interp-means-for-tf2-weapons'  id=\"boomdevs_4\" class=\"wp-block-heading\">What Interp Means for TF2 Weapons<\/h2>\n\n\n\n<p>A rifle shot and a rocket don&#8217;t reach a target through the same server mechanic. Neither does a Medigun beam or a Spy knife. Class labels alone aren&#8217;t enough, either. A Huntsman Sniper fires a projectile while a rifle Sniper uses hitscan.<\/p>\n\n\n\n<h3 id='hitscan-weapons'  id=\"boomdevs_5\" class=\"wp-block-heading\">Hitscan Weapons<\/h3>\n\n\n\n<p>Scattergun pellets, pistol bullets, minigun fire, shotgun blasts, revolver shots and standard Sniper rifle shots are hitscan. The server evaluates an immediate trace rather than launching a traveling bullet entity.<\/p>\n\n\n\n<p>Interpolation shapes where the remote target appears. Applicable hitscan attacks are evaluated by the server with lag-compensated player history. A smaller, stable buffer can show movement more recently. An undersized buffer on a jittery route can give you a rougher target to read.<\/p>\n\n\n\n<h3 id='melee-and-backstabs'  id=\"boomdevs_6\" class=\"wp-block-heading\">Melee and Backstabs<\/h3>\n\n\n\n<p>TF2 evaluates melee with server-side range and trace rules. Current TF2 scripting documentation notes that hitscan and melee processing requires lag-compensation information. The model on your screen isn&#8217;t the final ruling on whether a bat, shovel, wrench or bottle connected.<\/p>\n\n\n\n<p>Spy adds target orientation. Your client displays an interpolated player position and facing direction, while the server decides whether the knife attack satisfies its backstab conditions. Changing interp doesn&#8217;t extend the knife or guarantee the angle.<\/p>\n\n\n\n<h3 id='rockets-grenades-arrows-and-other-projectiles'  id=\"boomdevs_7\" class=\"wp-block-heading\">Rockets, Grenades, Arrows and Other Projectiles<\/h3>\n\n\n\n<p>A rocket, grenade, sticky, flare, syringe, arrow or crossbow bolt travels through the server simulation after launch. The target shown by the client still affects the player&#8217;s judgment, but the projectile isn&#8217;t an ordinary historical hitscan trace.<\/p>\n\n\n\n<p>A lower buffer can make visible movement look more current when the connection stays clean. It cannot make a rocket fly faster, shorten a reload, alter a grenade fuse or speed up a Huntsman charge.<\/p>\n\n\n\n<h3 id='medigun-and-mixed-loadouts'  id=\"boomdevs_8\" class=\"wp-block-heading\">Medigun and Mixed Loadouts<\/h3>\n\n\n\n<p>The Medic sees a networked patient moving through the snapshot system. The server still controls beam targeting, range, line-of-sight behavior, healing and \u00dcberCharge. Interp doesn&#8217;t improve healing output or build charge faster.<\/p>\n\n\n\n<p>A rifle Sniper uses hitscan, while Huntsman fires a projectile. Demoknight&#8217;s melee work differs from a Demoman placing stickies.

It doesn&#8217;t change fire rate, reload speed, projectile velocity, melee range, healing rate or damage.<\/p>\n\n\n\n<h2 id='ping-isn-t-the-whole-connection'  id=\"boomdevs_15\" class=\"wp-block-heading\">Ping Isn&#8217;t the Whole Connection<\/h2>\n\n\n\n<p>Two servers can show similar ping and feel different. One route may deliver snapshots steadily. Another may bunch them together, miss one occasionally or change delay from moment to moment.<\/p>\n\n\n\n<p>Ping measures round-trip delay. Jitter is variation in that delay. Loss means packets didn&#8217;t complete the journey. Choke points to updates being constrained by the available rate and networking conditions.<\/p>\n\n\n\n<div class=\"ti-interp__card\">\n<p><strong>Ratio 1:<\/strong> about 15.15 ms at 66 updaterate. Less buffer, with little spare room when a snapshot is late.<\/p>\n<p><strong>Ratio 2:<\/strong> about 30.30 ms. One additional snapshot interval.<\/p>\n<p><strong>Ratio 3:<\/strong> about 45.45 ms. More cover for instability, with more display delay.<\/p>\n<\/div>\n\n\n\n<p>Interpolation needs known states on both sides of the moment being rendered. If the next snapshot hasn&#8217;t arrived, the client can run out of useful history and fall back on extrapolation. It projects movement beyond the latest information, then may correct when fresh data arrives.<\/p>\n\n\n\n<p>A steady ratio-2 view is more useful than a ratio-1 setup that keeps producing pauses or corrections. A clean route may not need the extra interval. There isn&#8217;t one honest answer for both cases.<\/p>\n\n\n\n<p>If ratio 3 calms frequent interruptions, don&#8217;t stop the diagnosis there. Check whether the problem follows every server, along with local network load and Wi-Fi quality. A buffer can&#8217;t recover data that never arrived.<\/p>\n\n\n\n<h2 id='checking-your-tf2-network-settings'  id=\"boomdevs_16\" class=\"wp-block-heading\">Checking Your TF2 Network Settings<\/h2>\n\n\n\n<p>Type each cvar without a value to see what TF2 is using.<\/p>\n\n\n\n<div class=\"ti-interp__code\">cl_interp\ncl_interp_ratio\ncl_updaterate\ncl_cmdrate\nrate<\/div>\n\n\n\n<p>Run those queries again after connecting.

Current mastercomfig 9.100.1, dated July 3, 2026, still defines a diagnostic through <code>net_graph 1<\/code> and normally leaves it disabled with <code>net_graph 0<\/code>. The Valve Developer Community also maintains a <a href=\"https:\/\/developer.valvesoftware.com\/wiki\/TF2_Network_Graph\">TF2 Network Graph reference<\/a>.

Current mastercomfig groups Scout, Heavy, Engineer and Sniper under its hitscan policy. Soldier, Pyro, Demoman and Medic use its projectile policy, while Spy receives separate handling.<\/p>\n\n\n\n<p>Those are practical class defaults, not descriptions of every loadout. Huntsman Sniper is an obvious exception. mastercomfig provides <code>net_hitscan<\/code> and <code>net_projectiles<\/code> aliases for deliberately configured subclasses.<\/p>\n\n\n\n<div class=\"ti-interp__table-wrap\">\n<div class=\"table-wrapper\"><table>\n<thead>\n<tr>\n<th>Module<\/th>\n<th>Buffer at 66<\/th>\n<th>Purpose<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><code>snapshot_buffer=auto<\/code><\/td>\n<td>Class-aware<\/td>\n<td>Managed default<\/td>\n<\/tr>\n<tr>\n<td><code>snapshot_buffer=off<\/code><\/td>\n<td>15 ms<\/td>\n<td>Minimal<\/td>\n<\/tr>\n<tr>\n<td><code>snapshot_buffer=x1<\/code><\/td>\n<td>30 ms<\/td>\n<td>Extra interval<\/td>\n<\/tr>\n<tr>\n<td><code>snapshot_buffer=x2<\/code><\/td>\n<td>45 ms<\/td>\n<td>More protection<\/td>\n<\/tr>\n<tr>\n<td><code>snapshot_buffer=custom<\/code><\/td>\n<td>User-defined<\/td>\n<td>Raw cvars<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n\n\n\n<p><code>snapshot_buffer=off<\/code> doesn&#8217;t disable Source interpolation.

When accepted, the effective interval is about 30.3 ms.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Is cl_interp_ratio 1 better than ratio 2?<\/summary>\n\n<p>Not on every connection. Ratio 1 lowers the buffer to about 15.15 ms at 66 updaterate, while ratio 2 keeps an extra snapshot interval available.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>When is cl_interp_ratio 3 useful?<\/summary>\n\n<p>Ratio 3 can be a temporary fallback when late or missing snapshots still disrupt ratio 2. At 66 updaterate it creates about 45.45 ms of buffer, but it won&#8217;t repair persistent loss.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Does cl_interp 0 turn interpolation off?<\/summary>\n\n<p>No. TF2 uses the larger of <code>cl_interp<\/code> and <code>cl_interp_ratio \/ cl_updaterate<\/code>. Server bounds can also affect the accepted result.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can interp make rockets or arrows travel faster?<\/summary>\n\n<p>No. Interpolation changes how received entity states are displayed. It doesn&#8217;t alter projectile velocity, reload timing, fuse behavior, charge time or damage.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Can lower interp improve hitscan aim?<\/summary>\n\n<p>A lower stable buffer can show movement more recently.

An interp value can&#8217;t extend the knife or force the angle.<\/p>\n\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Is net_graph currently available in TF2?<\/summary>\n\n<p>Current mastercomfig 9.100.1 source dated July 3, 2026 still uses <code>net_graph 1<\/code>, and VDC maintains a TF2 network-graph reference.
