Need help optimizing OBS + Geometry Dash

[SuperKiwiTawa]

Hello all, I am new to the bitsum community. I hope you are all doing well. I only recently began to tinker with Process Lasso but I do have an educational background in Computer Science.

Today I am asking for help to boost my FPS in Geometry Dash while OBS is open. I need OBS to record and stream my in-game level completions, and I need high FPS in Geometry Dash.

Geometry Dash is single-threaded. I know this based on reports made online from other GD community members (Apparently, it uses OpenGL). The game appears to perform all of its work within just one of my cores.

Geometry Dash has a built-in FPS limiter, and the limit could go as high as 9999. It's normal and competitively advantageous to play levels at very high framerates such as 240, 360, 480, etc., and my goal is to play on the highest FPS possible.

When I stress test my CPU by playing a CPU-intensive section of a level, the utilization on one of my cores maxes out at a consistent 100%. My FPS at this section is 200 give or take. However, when OBS is open at the same time, it drops down to 150 give or take.

I was wondering... since Geometry Dash only uses a single core, I can have OBS excluded from using this particular core while it is open. I could set OBS's affinity and its process would never interfere with Geometry Dash. I have tried to do this but I am running into issues. I've pinpointed the CPU core Geometry Dash uses via Resource Monitor (I'm on Windows 10) and unchecked its affinity for OBS, but OBS still seems to interfere with Geometry Dash's FPS. I've set this affinity rule to "Always" but this does not help.

I've also run into glitchy audio issues with Geometry Dash, but I think that can be fixed by raising the priority on a particular audio-type process. I saw a video tutorial on that.

Please help me, I'm just a novice with PL but I feel as though this is a fantastic idea to optimize the game. Not only could it help me, it could help the rest of the community, especially those who play competitively.
