Ever since I picked up tower unite, I’ve always had a stuttering problem only on the gamemode virus, where seemingly randomly anywhere from half a second to 10 seconds the game is unresponsive. Nowhere else does this happen in the game afaik. Searching the steam forums and here, some other people seem to have reported similar problems on amd fx processors.
Recently however I found a fix for me, which was adding -nosound to the launch options. I did some searching and found some amd audio issues in unreal engine 4, perhaps this is related?
