December 31, 20223 yr Hello, Using P3Dv4(!!!) analogy, am I correct that in MSFS DX11 mode, VRAM OOMs aren't possible as the burden is on CPU's shoulders. I've completed 9 flights in MSFS with Fenix/PMDG/3rd party sceneries/PSXT traffic and had zero (knock on the wood) issues, even though MSI gauge constantly shows 10.7GB in use with my 2080Ti (12GB). Would appreciate clarification. 9950X3D, X870E ROG CROSSHAIR HERO, Corsair Dominator Titanium 64GB DDR5-6000 PC5-48000, ASUS RTX 5070Ti 16GB, 9100 PRO 4TB Samsung ,990 PRO 4TB Samsung, AX1600i 1600 Watt 80 Plus Titanium ATX, ASUS 360 ARGB EXTREME 360mm Liquid CPU Cooling Kit.
December 31, 20223 yr I'm not sure what happens when you exceed VRAM, but I do know MSI's OSD does not display actual VRAM in use by the sim, FWIW. For example, right now flying into LFPG and MSI shows 8.8Gb in use, whereas MSFS DevMode OSD shows 7.1Gb. Certainly have never had any kind of 'error' or problem when VRAM has approached all of my 12Gb--but I'm using DX12.

January 1, 20233 yr I believe DX11 will use normal, slower RAM when VRAM usage is exceeding. This of course leads to slower FPS. But maybe someone with more knowledge could correct this if I'm wrong. Edited January 1, 20233 yr by bvdboomen
January 1, 20233 yr I don't think it has anything to do with the CPU, but other than that you are correct. I also have a 2080Ti. Mine has 11GB of VRAM. Most of the time, it shows nearly all of it in use when MSFS is running. Same for GPU utilization. Almost always in the 95-97% range. Right where I want it. OOM crashes are truly a thing of the past. After a few weeks, you'll be able to forget that there ever were OOM crashes on final and focus on your flying.
