I recently built a new rig for MSFS that now has an RTX 3090 with 24GB of VRAM. I’ve tested my rig flying through Brisbane with both Orbx scenery packs installed. With texture resolution set to Ultra, i see VRAM usage >20GB in VR with an HP G2. A 3080ti has only 12GB VRAM. Sadly, the VRAM of a 3080ti is not enough for this combo. Lowering the texture resolution setting will help to keep VRAM usage in check. My old rig had a 2070S that i later replaced with a 3070FE. Both had 8GB of VRAM. I needed to set texture resolution to medium to keep this scenery combo within limit. If i recalll correctly, medium texture resolution used about 7GB VRAM and produced acceptable performance.
