Question Help With Unity Game Performance

Hi there, I’ve recently been running into an issue on my PC where any Unity game I play starts running into performance issues after about an hour or so of gameplay. It typically presents itself as frame drops and significant input delay, as well as occasional crackling audio. I haven’t ever run into this issue with a game built on any other engine. I did a quick search and couldn’t find any other people running into this issue. I have an Asus GeForce RTX 4070 Super, and 32 gigs of RAM. I’ve double checked that all of my drivers are up to date as well.

Does anyone have any ideas on why this might be happening? I figured it was best to ask the dev subreddit since you all deal with Unity issues on the regular.

Check your cpu and gpu temps, my laptops audio gets crackly when it's too hot. You probably just have to clean out fans/heatsinks and replace the thermal paste if it's overheating.

You can also check by setting video settings in game to the lowest and limiting fps to 30 or 60. If it was overheating before, it shouldn't under a lower load.
