Thanks for the feedback. Could you share your hardware specs? I’ve tested this on multiple hardware setups and haven’t encountered this issue so far, so this information would help me to solve it.
Yeah sure, I'm on a Thinkpad T14 with a i5-1335U, and integrated Iris Xe graphics and 32gb ram. The lag spikes happened every few seconds, so my intuition is that it's related to memory management or garbage collection or something that happens in the background, rather than raw frame rendering performance. I played the game on my external monitor which is a normal 1920x1080px.
