Thx - any details as to why, tough?

For me most of the performance issues with MSFS24 are now being VRAM limited. When they went to MSFS 2024 they rewrote for DX12 and while doing that upgraded a few things to look nicer. The texture management still seems to need some work.

This means that my 9800x3D/3080Ti 12GB sort of runs out of VRAM and pages when used in VR or 4K desktop. I'm in the position where the same visuals (scenery/aircraft etc) for MSFS2020 (using DX11) when compared to the newer MSFS2024 is just generally worse and a lower framerate. In VR a bad framerate makes things unplayable. For desktop use you have DLSS which helps a lot, but in VR that blurry movement really impacts clarity.

DLSS also blurs the cockpit displays quite badly when there's anything moving on them (airspeed/altitude tape, etc.). It looks like temporal blur, which is interesting because the same blur doesn't happen with their TAA (*temporal* anti-aliasing) implementation.

Yeah, DLSS looks great outside the window and for people enjoying GA and VFR it's all good. For airliners with digital displays it is harder to use, as like you said it blurs. They did talk about using some form of stencil/exclusion around cockpit displays but I think that didn't go anywhere as yet.

As a team they have a pretty tough job because the audience is all of the place for a title like that, as in people with 'I can see my house!' being made happy vs 'My pressurization gauge cross-bleed reading is below the Boeing B738 manual official figure, unplayable'.

		> They did talk about using some form of stencil/exclusion around cockpit displays but I think that didn't go anywhere as yet. They've been talking about that since the launch of msfs2020 and there's not been any movement on it as far as I know.

		Yep, that's the flight sim community in a nutshell.

I found DLSS4 Preset J much much improved, I prefer it to K.

That describes what I've seen. When I first compared 2020 and 2024 in as apples-to-apples a way as I could, it seemed like 2024's frame rate was about a third lower than 2020's. This was on a 7900 XTX with 24 gigs of VRAM.

I'm waiting for SU4 before I get back into it...

		VR situation was much worse. On the hardware where 2020 was OKish, 2024 was unplayable.
