I mean that's fair, and I am definitely going to. But it's also only this specific game that does it. I tested like 20 other games and no other game had this issue at all.
Like why would the GPU get pinned on this game-- on the title screen no less-- but not something like Cyberpunk 2077 with maxed out settings. That doesn't make sense and I can't even remotely understand why it would happen besides something in the game code/settings.
I tested a bunch of other unity games as well. All normal-- no problems. Nothing pinning the GPU at its max. Most games don't even take the GPU past 10-20% utilization. And even the most GPU intensive only sit around 60-80%.
The only difference I could easily find was in the Runtime Initialization AptivePerformance was turned on for this game. No other Unity game I checked had that.
Do I know if that's the issue? No idea. It was the only difference I could find with what I can check on my end.
All I know for certain is that this game is the only game to have the issue. And its very strange for only one specific game to have issues if its a system problem. So-- its at least worth mentioning
