I just opened UE5 yesterday and immediately noticed it was essentially unusable. I started with the FPS project preset at first but then also tried a blank project with no starter content. In both instances I was getting extreme stutter until it eventually froze and crashed. I initially thought the preset might have been set too high but at this point I hadn’t had a chance to add anything. Switching to medium had no noticeable impact.
Pulling up GPU-Z showed that I had extremely high VRAM usage. Again I haven’t done anything yet at this point besides trying to move about the scene a bit. I eventually noticed that if I don’t do anything VRAM usage stays constant, but if I use the cursor and even just highlight a tab VRAM usage starts climbing again and holds never falling. I have a screenshot of a test I did. I was at almost 20Gs after 1 minute leaving the cursor on the file tab.
I’m just wondering if anyone has any ideas here. I don’t think this is normal but I have no experience with UE5 either so maybe I’m missing something. I was really just looking forward to playing with the engine.
When I started Unreal was on 5.2 and the Nvidia driver was a couple months old I updated both. I meant to put that in the post and I forgot to add it. I didn’t realize Nvidia had a seperate driver but it does make sense. I’ll give it a shot later today. Thanks for your thoughts I appreciate it.
Unfortunately different drivers didn’t work. The problem still persists. The current studio version is at the current version of the gameready I had installed. I then tried to roll in back to the last studio version but no dice. I’ll keep trying things but I’m at a loss as of now.
Well it looks like I fixed it. I’m not sure what made me think of it but I have EVGA Precision X1 installed on the computer. I turned that off and opened a blank project again and the VRAM is holding at about 2.5Gs and the stuttering is gone. I’ll just uninstall that I guess. I’ll update if that didn’t end up being the cause but for now all is good it seems.
