CS2 Interp: What it is, All commands, Best settings

CS2 interp (also known as "interpolation") is a setting in Counter-Strike 2 that determines how smoothly the game renders movement between server updates.

Interpolation affects the delay between when a player's actions are registered and displayed on-screen.

Adjusting interp values can improve responsiveness but may cause visual glitches if set too low.

I've been playing CS2 since its release and have experimented with various interp settings to find the optimal balance for my gameplay.

In this article, I'll explain what interp does, list all the relevant console commands, and share my recommended settings based on extensive testing.


What is interpolation in CS2?


Interpolation in CS2, also known as cl_interp, is a crucial aspect of the game's netcode that helps create a smooth gameplay experience. It fills in the gaps between data packets received from the server, particularly for player movements.

In Counter-Strike 2, you receive packets of information from the server at a specific rate, usually 64 or 128 times per second. These packets contain updates about the game state, including the positions and actions of other players.

However, due to network latency and other factors, receiving these packets can be delayed or inconsistent.

This is where interpolation comes into play. It anticipates enemy actions between received data packets and fills in the gaps.

This process reduces jittery visuals and creates a more fluid gameplay experience. Consider it a buffer that smooths out the gameplay by compensating for these network inconsistencies.

But here's the catch: the interpolation time, effectively a "delay" your client applies to every player on screen, means you see everything just a bit later.

This delay can sometimes lead to players experiencing issues like dying behind a wall or solid object due to a certain lag or delay.

The higher value between cl_interp_ratio/cl_updaterate and cl_interp determines the interpolation time. For CS2, the default cl_interp value is set to 0.1 or 100ms.

The default cl_updaterate and cl_interp_ratio values are 20 and 2, respectively, which again creates an interp value of 0.1 or 100ms.

The game usually takes the highest value between these two and adds the interpolation time to the individual ping of the player.

In my experience, finding the right balance with your CS2 interp settings is key to minimizing potential gameplay issues while maintaining a smooth experience. It's worth experimenting with different values to see what works best for your setup and playstyle.


List of all CS2 interp commands


To optimize your CS2 gameplay, you can use these console commands to tweak your interp settings in CSGO:

  1. cl_interp 0: Sets interpolation to 0 (lowest value)
  2. cl_interp_ratio 1: Sets interpolation ratio to 1 (minimum value)
  3. cl_updaterate 128: Sets client update rate to 128 (highest value)
  4. rate 786432: Sets bandwidth rate to the highest value
  5. iv_off: Disables interpolation variable profiler

I recommend creating an autoexec.cfg file with these commands, which load automatically when you launch CSGO.

Experiment with different CS2 interp settings to find what works best for your setup and playstyle.


How to optimize your CS2 interp settings


To ensure a smooth gameplay experience in CS2, it's crucial to fine-tune your interp settings.

You can minimize latency, maintain a stable connection, and boost your FPS by making a few simple tweaks. Here's a step-by-step guide on how to optimize your interp settings:

  1. Open the CS2 console by pressing the tilde key (~) and enter the following commands:
    • cl_interp 0.015625 (for low ping and stable internet connection)
    • cl_interp 0.03125 (for high ping or less stable connection)
    • cl_updaterate 128
  2. To make these changes permanent and avoid resetting them every time you restart CS2, create an autoexec.cfg file:
    1. Navigate to your CS2 config folder (usually located at "C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\game\csgo\cfg")
    2. Create a new text document and name it "autoexec.cfg"
    3. Open the file and add the following lines:
      • cl_updaterate 128
      • cl_interp_ratio 1
      • cl_interp "0.015625" (for low ping and stable connection) or cl_interp "0.03125" (for high ping or less stable connection)
    4. Save the file

By setting cl_interp to 0.015625 or 0.03125, you make sure that your client interpolates between one or two ticks on 64-tick servers and two or four ticks on 128-tick servers. This helps bridge any inconsistencies between the player and the server, resulting in a smoother experience.

Remember, if you have a less stable internet connection, opt for the higher cl_interp value of 0.03125 to maintain a more consistent gameplay experience.

With these optimized interp settings, you can enjoy CS2 with minimal latency, improved FPS, and a stable connection.

Happy fragging!


What are the best CS2 interp settings?


As an avid CS2 player, I've spent countless hours tweaking my interp settings to find the perfect balance.

From my experience and research, the best CS2 interp settings, used by many pro players like s1mple and ropz, as well as countless FACEIT and eSports competitors, are:

  • cl_updaterate 128
  • cl_interp_ratio 1
  • cl_interp "0.015625" or cl_interp "0.03125"

cl_updaterate 128 sets the rate at which your client updates from the server. A higher value means more frequent updates, resulting in smoother gameplay.

cl_interp_ratio 1 sets the ratio used to interpolate between two snapshots. A lower value reduces latency, making the game feel more responsive.

cl_interp "0.015625" or cl_interp "0.03125" sets the interpolation amount.

Lower values reduce the perceived delay between your actions and the game's response. "0.015625" and "0.03125" correspond to interpolation times of 15.625ms and 31.25ms respectively.

These settings aim to minimize the lag between your actions and the game's response, which is crucial in a fast-paced game like CS2.

However, their effectiveness depends on your internet connection and the server's performance.


Why is CS2 interp important for your gameplay?


CS2's interpolation feature is a game-changer, filling in missing frames to create a fluid, jitter-free POV that feels like a smooth, full video. It's like watching a movie without any skips or stutters.

But here's the thing: the default interp settings can actually hinder your gameplay. With cl_interp at 0.1 and cl_updaterate at 20, you might experience significant lag, making enemies seem to teleport around the map.

Trust me, there's nothing more frustrating than lining up the perfect shot only to die behind cover because of interpolation delay.

That's why I always optimize my interp settings in my autoexec.cfg file.

By tweaking these values, I can reduce lag and improve my in-game performance.

So, don't overlook interpolation if you're serious about elevating your CS2 gameplay. Experiment with the settings, find what works best for your setup, and enjoy a more responsive, immersive experience.


Can CS2 interp default settings worsen your gameplay?


Yes, CS2 interp default settings can worsen your gameplay if you have high ping, latency, or low FPS.

I've found that adjusting my interp settings based on my connection and system performance significantly improves my CS2 experience.

Sticking with defaults isn't always ideal. The right interp value depends on your specific setup.

Too low, and you might see choppy movement. Too high, and your actions will lag behind the server.

Remember, everyone's different. What works for pros or friends might not feel best for you. Trust your gameplay and adjust accordingly. With some trial and error, you'll land on interp settings that elevate your performance.


What are the default interp settings in CS2?


Here are the default interp settings in CS2:

  1. cl_interp: The default value in CS:GO and CS2, set by Valve, is 0.1 or 100ms. This CS2 interp setting is the interpolation amount, bounded on the low side by server interp ratio settings.
  2. cl_updaterate: The default value for cl_updaterate is 20. This determines the rate at which the client updates the game data.
  3. cl_interp_ratio: For cl_interp_ratio, the default value is 2. This ratio is used to set the final interpolation amount.

Is changing CS2 interp settings risky?


No, changing CS2 interp settings is not risky when done carefully.

As long as you make incremental adjustments and monitor your system, experimenting with CS2 interp settings is safe.


Will interp settings fix all lag issues in CS2?


No, interp settings will not fix all lag issues in CS2. While optimizing your interp settings can help reduce latency, high ping and an unstable internet connection can still cause lag.

Use the netgraph command to monitor your connection quality.


How do you create the autoexec.cfg file for CS2?


Here is how to create the autoexec.cfg file:

  1. Open Notepad or your preferred text editor.
  2. Enter the commands you want to be executed every time CS2 starts. You can use a configurator to generate these commands easily.
  3. Go to File > Save As... and select "All Files (.)" from the 'Save as type' dropdown menu.
  4. Name the file "autoexec.cfg".
  5. Navigate to the CS2 config folder, typically located at "C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\cfg", and save the file there.
  6. Launch CS2 and the game will automatically execute the commands in your autoexec.cfg file.

Remember, any changes you make to autoexec.cfg will take effect the next time you start CS2. If you're already in-game and have made changes, simply type "exec autoexec" in the console to execute the new commands without restarting.
