Easily the most impressive piece of software I've ever bought or imagined. With my lowly 4070 the performance is sublime.

12 GB Vram at limit here, TAA 90 + DLLS.

Am I just imagining it, or has the big performance boost with the early builds in SU4 been eroded with successive builds? I’m fairly sure the old FPS counter has taken a bit of a dive but maybe I’m hallucinating.

I know there are a large permutation of different PC specs out there, and people running different setups, sim settings, and background software, but every update, the feedback is the same. 
Some people saying it is the best implementation they have seen, and others saying they have lost performance.  It is virtually impossible to gain any reliable information from this.
I suppose all you can do is try things for yourself.

Nope not imagining it. The first builds were almost perfect lol. Now it’s been regressed back to SU3 levels.

Hoping that maybe they had to put in some debug code or just increase debug levels to chase something down and that is slowing things down but will also be backed out... 

I also noticed a regression in performance of beta builds since the start, that was with my old GPU at the time though as since I've upgraded it's been hard to tell! 

It does seem to be a trend in most/every beta period though, the early builds are great then there's a gradual decline.

Performance feels the same to me.

try clearing your caches.

The last two builds introduced stutters I never had before. And yes, I cleared caches.

ahhh.. thats a shame, i was about to jump into it but will have second thoughts now...what a pity

Actually, im just curious about the process here based on the above feedback..

When they make a Beta build and everyone raves about how good the performance is... do the programmers 'lock' that data in so it remains throughout? Or when they change other stuff, do those changes somehow affect the data that made the performance good?

Probably not explained that well, but wonder why the degradation when things were going really good? And.. do they notice it?
