CS2 Performance Solution (on nvidia)

[baaked]

My computer is a bad-ish mid-range gaming laptop from mid-2021.

This means Optimus, and the Intel Integrated graphics also sits between the pipeline, but things are actually playable for me after doing this simple thing.

In CS2 on a fresh Windows install I was getting a 0.1% frametime of up to 50ms, which created a pretty visible stutter, and it was when I was rezoning between the voxel lighting zones CS2 uses for stuff, so every time I swing anything interesting. It was bad! It was so bad that I installed superluminal a few weeks ago just to verify that it wasn't cs2.exe game code, but rather an nvidia library routine where the game was hitching so much (I created a unique pattern out of the hitches with my movement, and followed the trace down).

The only solution I could find was to revert from the latest nvidia driver to the "game-ready driver" for CS2! The driver version is 537.42, and it's available here: https://www.nvidia.com/download/driverResults.aspx/211709/en-us/

⚠ Warning: This is NOT the newest driver, and any updates will revert. I've tried the 545 branch drivers, and things get worse!! You can use NVCleanstall to disable any bloat, and prevent automatic updates.

I did search and don't see any other discussion about this, but performance has been intolerable with any other driver.

This has considerably improved my 0.1% frametime, and overall fluidity. I still only max out at around 150, and I still see dips to 60fps or a 16ms frametime, but it isn't as frequent or correlated with gameplay.

Have you tried using Ethernet or making your router closer to your PC? I did this with my 2018 laptop and I haven't even gotten a single lag spike

What? I'm talking about frametime, not network latency, but since you asked:
- I'm the only device connected to the router, via 1GbE NIC.
- The Windows network stack is configured to disable everything basically, save IPv4
- The router is connected to the DOCSIS 3 modem, again, via 1GbE-capable Ethernet NICs.
- I've taken great pains to disable any services that might unexpectedly schedule any resources on the computer, or prioritize them lower than CS2.

But anyway, I needed to upgrade my router because under testing at full capacity my previous router was exhibiting queueing behavior and delaying packets.
