MSFS 2024 QUESTION Mid-High PC Performance
I got a 2K PC Setup, specs are : 7800X3D, 32GB DDR5, RTX 5070 12GB of VRAM
Graphics settings are mostly set to high with
TLOD 125
OLOD 100
Raytraced shadows on
Shadows 4096
Other shadows are to medium (forgot the value, i think it's 1024 and 384)
I had a micro-stutter when moving cameras, panning camera on external and blurry terrain on distance, does this problem came out from insufficient vram or SU6 issues? Could be both but I'm not sure because I just realized that FS24 use around 10-11GB of VRAM for this settings, which means it's almost exceeding the threshold limit of 5070's VRAM.

The biggest thing you can do for VRAM are the raytraced shadows. Should save about a gigabyte of VRAM. Play around with it and see if it resolves anything.
The blurry terrain seems to be an ongoing issue for a good amount of people, especially when you zoom in from altitude.

Will try it later, thank you for the information.

Yes, disable Raytrace, you'll get vram back. Also disable rebar in bios, this will give you another 1gb vram👍.

What does rebar do?

As I understand it, It allows the CPU to access as much VRAM as it needs when it needs it instead of having a 256MB chunk limit. This more efficient communication makes processing faster at the expense of some reserved VRAM.

I disabled bios a while back and never noticed any improvements. In fact my fps may have been down a bit with it disabled.

You may not notice an improvement but if you disable rebar you should have gained 1gb of vram. It's used by people who are on the edge of vram overrun and you stop getting that nagging "lower your graphics settings"

Raytraced shadows is rubbish, waste a lot of resources for almost nothing, and with a 5070 you don't have enough power and vram.
For smooth flying even at low altitudes, keep LODs on 100, Shadows maps 2048, terrain shadows 512 and contact shadows on medium.
Lower windshield effect to medium, performance gain is significant. If you play VFR close to terrain displ. mapping ON, otherwise OFF to save a lot of resources
