Re: [PC] FPS drops After 1.6.0 Update
So i haven't tested this since patch 1.7 but i know it was still there in 1.6 and seems people are reporting it as still here in 1.7, It's noteworthy that this end of stage performance drop is fairly reliably repeatable, you can even see where it starts and stops if you watch the replay and run it to a specific point forwards and backwards. I have seen it occur in various stages and locations and believe it's always the same stages and locations(location meaning the same actual spot on the stage, possibly a pacenote?)
I first encountered this last year when i did some performance tests after upgrading from a Ryzen 3600 to Ryzen 5800X3D:
at this particular point, near the start of the very last sector (for this video 17:46), the Ryzen 5 3600 somewhat keeps it's performance level and CPU usage consistent.

however on the Ryzen 5 5800X3D at the same point of the stage(for this video 17:23) you see the performance and consistency drop, frametimes increase and GPU boost drops, utilization becomes erratic and spiky compared to the Ryzen 5 3600

At the time i was power-limiting the 5800X3D and presumed that might be the reason and then things got busy and i couldn't investigate, i have found however that clearing my power and thermal limits didn't eliminate this end-of-stage performance drop, I thought itmight be the game's interaction with the 3D V-Cache but i see various users here with non-x3D V-cache processors reporting the issue, perhaps it's related to core count and thread scheduling?
When i find time i want to do these checks again but It might be really useful for it to be checked on Intels latest Presentmon closed beta, perhaps the new ability to measure simulation time error/animation errors could be relevant here?(Gamers Nexus covered this new performance metric here: )
