A bit at my wit's end here. When testing the 3.18 PTU, I thought the frame-rate loss I had was due to the diagnostics etc behind the scenes. In 3.17.2 Live I was getting 50 - 70fps fairly consistently (sometimes I'd go back to play Live just for the nice framerate). This was running everything at full, 4k resolution. In 3.18 Ptu I was barely getting past 30. This has carried over to live - I've not seen anything higher than 45fps. On the main deck of Baijini Point at the moment, for example, I'm getting between 18 - 25fps. Arena commander, Dying Star, Vanduul Swarm I was able to get 45fps max. My setup: i5 12600k 48gig of 3600 DDR4 ram RTX 4090 Win11 Running on an SSD When running 3.17.2 my computer was actually a little worse - with 32gig RAM (not using XMP), and a 3080. I don't think it's the e-core problem, because I had the same issue on Win10, and I've used process lasso/bios to disable e-cores. Barely makes a difference. Changing resolution/lowering settings does nothing (maybe a few frames here and there). Does anyone have anything else I can try?
