DX11 or DX12 for VR?

[Ramasurinen]

It can be quite system specific, but if you have a high end GPU (3090, 4080 or 4090) then DX12 should generally perform slightly better. Prior to SU14 there was a major memory leak in DX12, resulting in severely reduced performance after ~1-2 hours of flight, but happily that has been fixed. VRAM usage in DX12 is quite stable now, and reasonable, unless you’re using dozens of major scenery addons.

There is one bug peculiar to DX11 which keeps me flying in DX12 though…

[Strange stutter] When the sun is at 180° of the camera u get a stutter

Are you using Developer Mode or made changes in it? yes and no Have you disabled/removed all your mods and addons? yes Brief description of the issue: There is this strange, very strange stutter issue that has been around for many months. a friend raised this issue and i thought “surely not comeon” and well it sure did stutter. When the sun is at your 180° so directly behind you,the moment you pan your camera around you get this massive big single stutter. Provide Screenshot…

This problem is only noticeable in DX11, and it is very noticeable. Once you’ve seen it then it cannot be unseen. It technically does still happen in DX12 as well, if you carefully monitor the FPS debug window, but its effect in DX12 is so minor and brief in actual flight that I’ve never once been bothered by it.
