Unity is currently running very choppy, around the 15-20fps mark inside the editor and also when running the game. This does not improve when exported or ran inside release mode. Unity used to run fine until recently when I updated it to 2018.3.11 and upgraded my GPU to the RX 570 8GB. Because I did both at the same time, it’s hard to isolate the problem. I’ve reverted back to old versions, but Unity now runs horribly regardless of which version I run, rendering all of my work useless. I tried completely uninstalling Unity Hub and all of the versions of Unity I had, then reinstalling it, but the problem still persists.
I checked task manager, and CPU usage is around 15%, with RAM usage around 40%. My PC is very powerful and can run all the latest games, applications, etc, on full settings at blazing fast speeds without any issues whatsoever. I ran the Profiler, and it says that it’s running at thousands of FPS (when disabling VSync), despite it running terribly. I also tried forcing Unity to open in OpenGL mode, but this has not affected its performance. All I can think is that maybe it’s trying to run on integrated graphics and not registering my GPU. However, my old laptop had a terrible GPU an it ran much better than this. Could it be fixed through the AMD control centre?
Lastly, the game is running at double speed. The movement of the player, enemies, props, projectiles, animations, etc, all seem to be sped up way faster than before, while drawing horribly choppy and laggily (if that’s a word) at the same time.
I am completely beside myself. I have absolutely no idea how to fix this issue. I’ve been trying for days and I’m at my wit’s end. Nobody seems to be able to supply an answer. I’ve extensively Googled this problem for hours at a time, asked all my friends, posted on forums, asked colleagues and more, but nobody can help me. I have a huge work assignment that needs doing within Unity, and if I can’t get the editor working properly then I’m finished.
Any help would be greatly appreciated. I’ll return the favour in any way I can, whether you need art resources, debugging, code, etc. Thanks in advance!
