I got to run a little experiment yesterday.... buddy of mine is upgrading platforms and sold me his used 5800X3D for not a lot, so I decided to try it out.
Original system specs:
ASUS ROG B550F
5900X (slight overclock)
ASUS TUF 3090TI (custom overclock / water cooled)
64GB DDR4 @ 3600MhZ
HP Reverb G2
OpenComposite / OpenXR
After the multithreading update the 5900X was heaps better compared to previously, and I was happy with it, but in VR I'd get screen door effect occasionally (usually when I'm parked on the tarmac, and another plane whizzes by), there would be a lot of micro stutters that would sometimes prevent me from easily using the mouse in stressful situations, and there would be a noticeable FPS drop if I dropped down in a dense area close to the ground (which is to be expected, somewhat).
All I did was swap the CPU to 5800X3D, all else was the same - and it was a night and day difference in VR. WAAAYYYY smoother, loading times seemed to have decreased a lot, and I haven't really come across the micro stutters or screen door issues anymore.
Basically the point of this post is: if you have a 5900X or 5950X and can maybe get a 5800X3D cheap, and your primary concern is VR games..... do it.
BUT here's the caveat:
For VR, the 5800X3D beats the 5900X. Hands down, no contest. However, the 5900X does literally everything else better (in my rig anyhow). The 5900X does in fact run all the games I tried (@1440p), with higher FPS and better 1% lows (Cyberpunk w/o ray tracing, RDR2 max settings, Jedi: Lone Survivor max settings) vs 5800X3D. And, the 5900X definitely performs productivity + compiling tasks much more effectively - it's a massive difference on that point. This goes in line with some of the reviews and comparisons I've seen, but for whatever reason, my system config displayed more favorable stats for the 5900X, in 2D games, at 1440p - when compared with some stats and reviews online.
So if it wasn't for DCS VR.... I probably would have stayed with the 5900X. It's still a fantastic CPU. For now though, specifically for DCS, I'll be rockin the 5800X3D.
Hope that helps someone make up their mind, if a similar situation would arise.
