i7 9700 RTX2060S 8GB 16GB RAM
Played a couple of days ago post-patch with my usual settings (everything maxed in settings, 2k res, FSR on and set to Ultra Quality - I also flushed the shader cache files beforehand just in case) and had a less stuttery experience in general, but interspersed with more severe freeze/lag spikes that would recover after a second or two - as if assets had to get loaded in - this happened quite often when walking around in settlements. So it'd be smooth (almost constant 60fps in one particular agri settlement) and suddenly drop to 20-30 only to recover again to say 50. It wasn't better per se, more different (and I wasn't impressed overall). Switching to CAS didn't make much of a difference (the fps boost wouldn't be as high, while the image quality, at least if keeping SS to 1.0, would be better at least due to the sharpening effect).
Last night I decided to switch off all of that AMD malarkey because I'm well and truly sick and tired of the lower res/blurry image it comes with, and just go all in on the settings with SS @ 1.0 still. Concourse (didn't try planetary which are still much worse than the rest, although somewhat improved since patch 8) was disappointing enough, mid 40s with some stutter, but not as bad as pre-patch 8. I have a g-sync monitor so that will also help, especially if framerates don't jump all over the place.
I then went to a random settlement (daylight), think it was a low sec Industrial one. Messed around a little, killed a few NPCs where needed, nabbed the power regulator. Mostly 50-60fps throughout, with little stutter. Same thing planetside (with nothing else in view, i.e. no settlements/plants) - though it was quite a featureless and dull airless icy body. I was a bit surprised because could it be that FSR/CAS is causing more harm than good now? Or was I just lucky going to locations that don't suffer as much from performance issues? It was by no means perfect but it was a lot better than at any stage previously, given the settings I used.
The worst of last night's session was the galling 1-2 second loading in of stations and FCs (how on Earth they left this in the patch and/or didn't notice is truly beyond me) - that is bad enough to deserve a hotfix tbh. Other than that it was actually quite an enjoyable session. I fear however that by saying this I jinxed it and the next one will be a nightmare again performance wise. It's all so horribly random. But it did make me also wonder whether it's a CPU bottleneck now as others have suggested already.
