Can someone give me an idea how much FPS improvement I could expect in VAM VR from upgrading:
Current setup:
- i9-13900KF
- 64GB DDR4
- RTX 4090
Planned upgrade:
- Ryzen 7 9800X3D
- 64GB DDR5
- RTX 4090
Right now, I’m getting around 45 FPS in heavy JPXRZ scenes, and my target is a solid 72 FPS for VR.
Would the CPU + DDR5 upgrade alone be enough to get close to that?
Or is the 4090 still the bottleneck in VAM VR?
If a 4090 is not enough, do you think a setup with:
- 9800X3D
- 64GB DDR5
- RTX 5090
could realistically hold a stable 72 FPS in heavy scenes?
Would appreciate feedback from anyone running similar setups in VR.

Hi!
If you need my 2 cents, I think it depends. 9800X3D is the king at the moment, but your 13900KF is also solid. In thr benchmark the baseline 3 test phyics line is the closest indicator of how well a cpu performs, but to be honest the current gen of hardwares have already outgrown this plugin. Someone might make a new one once, but don’t hold your breath..
So in my opinion you have 2 options:
A. Fiddle with settings:
- that raptor is highly tuneable, also the ram handling is pretty good and profits a lot from it - but you need to know what you are doing..
- you didn’t mention, but here is a cpu patch in the site, its not an ingame plugin, but a couple files, which actually really works. It might be beneficial to read a bit, because it is configurable, but worth it. Basically free performance on the table (on top of anything else you do!)
- Fiddle with ingame settings. Monitor your he during play and see where and when it gets bottlenecked. If gpu, you csn simple lower resolution, change vr fov (or whatever its name where the edges getting downscaled..) etc - lots of options. The 5090 is the king without doubt, but the 4090 is a beast too. Of you are not fixated on native 4k res, then you actually cant even push the 4090 to limits.
Spottinh CPU bottleneck is a bit more tricky. Since Vam uses fewer threads, you need to check thread usage. Which cores are utilized, what GHz can it hold while you trash heavily. If you notice that it is heavily hitting a wall and limiting framerates, then try fiddling with physics settings. Lowering a bit, changing caps, checking scene contents settings (hairs, cloths, everything uses) or using the give me fps boost plugin also gives experience what phyics changing could mean swiftly.
- How do you use VR? Its also counts a lot. Steam takes a ton of perf penalty, use virtual desktop or cable.
B. If you want to buy:
- I wouldnt really recommend right now, but if you want to burn the money take the 5090. I doubt that the 4090 is bottlenecking, but at the blackwell is clearly superior
- Dont spend on cpu or platform. Altough the 9800X3D is AM5, which means you can swap easily to zen6x3d when comes out, but Intel is releasing nova lake at this autumn, which could very well be a turning point. They failed spectacularly for years, and this is their last chance and - altough I hate leaks - every cue hints that they taking themselves seriously this time. Also they promise longer platfrom support. And its just a couple more month. AMD also hints massive performance leaps with zen6 next year - it seems they somehow started to fear Intel comes out with something genuinly good this time.
Sorry for long post, I hope it might help a bit.
