7800X3D and RTX 4090 performance issues

Not 7800X3D but in theory the 7800X3D should be better than the CPUs in these videos.

Theory isn’t proof.

There is a user here on the forum who had a 7950X3D first and bought a 7800X3D at release and tested it.

He had worse performance with the 7800 and sold it and retained the 7950.

7800X3D Performance reviews for MSFS

Well, I got my hands on a 7800X3D yesterday and spent all night and this morning testing. And my conclusion was that at least for me, the 7950X3D was 6-8 fps faster than the 7800X3D. Not only that, but the 7950X3D had 7-10 better fps low’s as well. This might not be a huge difference, but as we all know, MSFS dreaded stutters is what one is always trying to get better performance. The 7950X3D just felt smoother. I did do a whole reinstall of windows just to make sure the 7800X3D was not leaving …

I’m not experiencing stutters, other than the occasional as I fly into a heavily detailed AP region and/or with 3rd party airports as the detail is loaded in. I don’t really get stutters on the ground, but I do see my FPS tank pretty signifcantly.

FSLTL is robbing me of 10-15 FPS and that is with the radius set to 10 KM! I have not found a way to get FSLTL to not do this. I’ve messed with its settings and had little to no results in improvement.

If I turn FSLTL off, I can get near 60 FPS on the ground. Panning around still really hurts.

Again, I’m running at 4K.
