June 3, 20179 yr Hi, is there a maximum amount of VRAM the sim will use? I'm asking because I can't get it to use more than 7-8GB (my GPU has 12GB VRAM) and I had some situations where I thought "why doesn't it have this in vram?" like when I flew over EGLL and when I looked back over my shoulder all airport buildings were textureless/black and it took a second to re-load the textures which were already there 10 seconds ago. With TEXTURE_SIZE_EXP=10, LOD_RADIUS=14.500000, all Settings @max and ORBX-England I get to 7.3-7.8GB VRAM. I thought it might be because I only use 1080p, but even with DSR@4k the VRAM consumption did not change. So could there be a limit, e.g. 8GB? (I never saw over 8GB VRAM usage...)

June 3, 20179 yr I was wondering the same thing, but in my case it looks like my regular ram is capped at 8gb. John

June 3, 20179 yr Yeah 8 seems to be max to for me 2, tried texture_size 11 and 12 but just kills scenery. UserBenchmarks: Game 147%, Desk 145%, Work 106% CPU: Intel Core i7-4790K - 101.5% GPU: Nvidia GTX 1080 Ti - 189% SSD: Samsung 960 Evo NVMe PCIe M.2 500GB - 259% Andy Slof

June 3, 20179 yr What is the default texture size= XX ? David Murden.

June 3, 20179 yr Perhaps another line in the config file somewhere which limits maximum VRAM usage because Rob Ainscough definitely stated he observed VRAM usage at nearly 11GB utilizing a value of 10 for the TEXTURE_SIZE_EXP setting.
June 3, 20179 yr Running TEXTURE_SIZE_EXP=10 and i've never gone above 7.4GB VRAM used. I've got 12GB to play with. No matter what setting i throw at it, it's not using more.
