КС2 дёргается, хотя FPS 400? Вот почему — и как я это убрал

Summary

The creator investigates why CS2 can feel choppy despite showing high average FPS. Their central point is that 1% low FPS and frame-time consistency matter more than average FPS: unstable frame delivery can make the image feel uneven even when average FPS is around 387.

The creator reports these results from five runs of the same benchmark:

• Default settings, no FPS limit: 387 FPS average; 1% low of 138.
• In-game Reflex + Boost and NVIDIA “Ultra” settings: Little change; 1% low of 141.
• fps_max 240 in the console: The game reportedly failed to hold 240 FPS, averaging about 220; 1% low fell to 109.
• Creator’s RivaTuner setup: A steady 240 FPS and a 1% low of 193.

The creator also compares frame-time variation: about 1.5 ms with no limit, 3.5 ms with the console FPS limit, and 0.2 ms with their setup. They attribute the smoother result to RivaTuner applying an FPS limit through NVIDIA Reflex, while CS2’s own Reflex is disabled.

These are the creator’s reported results, not a guarantee for other systems.

The video briefly covers earlier troubleshooting. The creator had tried a custom resolution through CRU and Windows 11. They also say that cleaning dust and replacing thermal paste lowered temperatures and removed some small freezes, though stuttering later persisted during matches.

Setup Guide

The creator says this method is for NVIDIA graphics cards only:

1. Install MSI Afterburner from its official site. RivaTuner Statistics Server installs with it.
2. Open RivaTuner, add cs2.exe, then close RivaTuner fully.
3. Replace the generated cs2.exe.cfg in the RivaTuner Profiles folder with the configuration linked in the video description.
4. Restart RivaTuner and enable Start with Windows.
5. Set the FPS limit to a rate the PC can sustain in demanding fights—not simply the monitor’s refresh rate.
6. Add the suggested launch options:

text -console -mainthreadpriority 3 -High -noreflex +fps_max 0 -allow_third_party_software

The creator says -allow_third_party_software is essential for RivaTuner to hook the game; -console and -mainthreadpriority 3 are optional.

1. Set NVIDIA Control Panel Low Latency Mode to Off. The creator also provides specific CS2 video-setting recommendations.
2. To undo the changes, disable RivaTuner autostart, remove the launch options, and restore NVIDIA settings. If the setup does not work, the creator suggests restoring HPET to its default setting. For Windows 11, they also suggest disabling the listed graphics toggles and restarting.
