I have used MSFS for many years in 2D but would like to try VR . At present I have a 10700f with an RTX3090 and 32gb of ram. Will this be enough to enter the world of VR, or will I be tweaking settings for the rest of the year to achieve a useable FPS. My machine is an Alienware so is at the limits of its upgradeability and Im not feeling a complete new system at the moment. Any advice welcome from anybody with a similar spec machine already using VR
That will be plenty. Use DLSS Balanced or Quality and you can find good settings for a rather smooth experience.
Thanks for the reply . I have never seem to have any gains with DLSS, seem to be very CPU bound . I’m getting a steady 40-45 fps using TAA with DX12 which is fine, just wondered how this would translate to VR
Which headset are you planning to use?
Well, VR is the one thing in MSFS that’s sure to relive you of CPU bottlenecks
Like others before have said, VR is a quite different from 2D gaming. You need all the frames you can muster, because it is basically two 4K monitors strapped to your eyes. And if you turn your head, the system needs to react very quickly. On a 2D monitor it actually has time to know where you are going to look before you actually look. You take the mouse, click and start to drag in a certain direction. At that point, the system can afford some latency to do a lot of stuff before it actually starts moving. Even if the movement is not super crisp, you don’t really notice because you are interested in the end image. If you activate certain camera positions, it again can do what it needs to do before it’s actually doing it. All kinds of time.
In VR, there is none of that. There’s maybe a little prediction going on, but latency needs to be minimal, not just small, minimal. This takes everything out of your GPU.
The main slow down factor in VR graphics is video memory. Copying stuff over the bus is the slowest operation of all, and the GPU is kind of throttling at that point, starved for work.
This is the most misunderstood aspect of stutters. You have CPU, GPU and Bus. The Bus is the slowest.
So memory wise you are good. Then you need to get the GPU to crunch as many pixels as possible in the shortest amount of time. DLSS will help you massively there. You can even use it to still physically render at native resolution, by selecting a higher resolution in some toolkit ( SteamVR, OpenXR Tools, OpenXR Toolkit, … ) but get nice AI powered upscaling, which when downscaled again in the headset gives you nice sharp lines, and minimal Moire effects.
Thats another question I’m open to suggestion . I was thinking HP reverb V2 ?
Thank you for the information , very informative
If your budget is limited Reverb G2 is good for starting. Consider looking for discounted price (it’s discontinued by HP) or even used at bargain price.
You may have more advice on the VR subforum.
