AMD vs Nvidia - VR edition

Anyone know what sort of improvement you can get going from 3900x to 5900x? - I'm mainly a sim racer with some flight simulation as well.

Trying to decide how best to spend up to about £1000 - either CPU or GPU, or just wait!

According to this video @lokiss found, it's a pretty significant difference - certainly from 3700x anyway.

Thanks - yes, saw that video and I'd assume it would translate to 3900x v 5900x, dependent upon capability of GPU.

Would be great to have someone's first hand experience as I can't help but think money might be better spent on GPU for biggest improvement and then CPU later.

Guess I could run fpsVR in each of my sessions and muck around with settings to check extent of CPU v GPU bottlenecking with current settings and what I would ideally run, e.g. no. of AI, level of supersampling, etc...

5 months since the 3000 series release and I still have no real idea if AMD would be worth a buy this gen, mostly as the AMD cards seem even more rare than the Nvidia ones.

In hindsight I'm extremely pleased I managed to snag the 3080FE but I still feel like there's quite a lot more to come with drivers, just hope there's some real focus on improving VR performance, still dropping frames all over the place even with the newest driver which is meant to address that.

Anyone on here got their hands on an AMD 6000 series card and tried in VR?

I'm hoping we'll get DLSS for VR, which should make a huge difference in performance.

Think it's techincally possible right? We're just waiting for it to be implemented in a game. Would have to be an AAA title, something like ACC would be a perfect candidate, given the performance leap to be had in VR...

Babeltech do reviews. Nvidia is still better for VR than AMD.

Yeah, have seen that. Was wondering whether we had any first-hand knowledge on here of the AMD offerings in VR.

Yeah as of DLSS2.1 they added support for VR and announced integration into UE4 but to date no one has actually used it to my knowledge.

I wouldn't hold out hope for ACC as they are still on DX11 and an older branch of UE4 that they have no interest in leaving due to the heavy physics engine customisation work and the need to port that to any new branch.
