CSGO lag/desync while other fps games runs perfectly

[KappaKaaNo]

Just forget about csgo, its almost dead game rn. Its not worth it. Focus on cs2. Same problems on new engine version?

1.4m -+ current players is NOT dead my friend.

when it comes to GPU load, sometimes spiking to 100% even on 1280x960 resolution compared to 1080p in val.

Spiking to 100% GPU is less than ideal for many reasons, especially in a CPU bound game...

The first thing I would try is fps_max 200 and compare how it runs. If you can record your game with net_graph on it could be helpful for comparison.

Someone recently mentioned screen scaling could potentially create a gpu-bound scenario, are you using display scaling or GPU scaling in nvidia?

Do you have hardware accelerated graphics processing enabled in windows? I've noticed whenever it activates, the GPU usage spikes up like 80% just when browsing the web, and have disabled the setting due to that. If you have it on, maybe it's what causes the 100% load spikes.

Are you using Ultra Low Latency Mode in nvidia control panel? This setting is meant to leave some space for inputs to be received and processed while GPU is overloaded, but I'm not recommending it because I found huge performance decreases when using it and/or gsync.

Your GPU might need new thermal paste... if it's hitting 100% load it will be thermal throttling the performance if the cooling isn't still doing a great job. This would also explain why games with less load and heat would continue working normally.

Try to use better translation of my message next time, pls. I was talking about this, current source 1 engine version (which starts from 2004 y with tons of spaghetti code over it )of the game
