Unity-engine games run really slow (recently upgrade hardware)

Hello All-

So I recently made a new PC (13th gen Intel CPU, DDR5 memory, RTX 3080) and noticed that some of my games were running really slow when they previously did not on my older PC.

The first game was Untitled Goose Game, which basically failed to load. I could hear music but the screen was blank (or rather, it was showing my Windows screen) despite the tab for the game being on my taskbar.

Then I next noticed it on Cities: Skylines. Game was a straight stutter, couldn't even navigate the menu.

Then I finally noticed it on Desperados III, the lovely stealth game from Mimimi. Crashed twice, then loaded once but, again, stutter.

So I did a quick search and what do these games have in common?

UNITY game engine!

So I was curious if anyone on here has a fix or has heard of this before. It's very frustrating because Unity is not a demanding game engine, nor are these games particularly taxing on my system (or rather, they shouldn't be)

Thanks in advance.

Well I updated my drivers and that seemed to do the trick.

That's the default advice I guess for problems like this but I feel like it is the first time it's ever actually solved my problem 🤣😜

Poor Unity getting no love.

I actually think it's a cool engine (I'm not a professional though, just from a consumer standpoint I mean). It's not the prettiest engine but it does the job well as far as I can tell.

Lots of good games use it.

Sometimes I wish we could mark the correct answer in a thread to help others if they experience the same issue.

Yeah it is a nice feature, at least on the Steam forums (which iirc is the only time I've seen it used).

Did you do a fresh install of windows?

Also you can force perfer max performance with game profiles in the nvidia control panel

Yup, fresh install.

I did try to play around with the control panel but I must have been in some safe mode or something.

Anyway, it's working now (see above) after updating drivers. Which I thought I did when I updated everything after my windows install, but I guess maybe nvidia released a bad one? *shrug*
