There’s something interesting about the 517.40 studio driver from Nvidia. Using DX12 with a 3090, I’m seeing an increase in FPS compared to the previous driver, as well as reduced stuttering while panning. However, this seems to come with higher VRAM usage, where I’m seeing >1 GB of more VRAM usage compared to the previous driver. I suspect this is due to the enabling of DX12 memory optimization features with this new driver, as detailed in this post below. This seems to suggest the new 517.40 studio driver does actually trigger the DX12 memory optimizations within MSFS, as VRAM usage is increased and performance is improved on the new driver when using DX12.
