May 7, 201115 yr Thanks a lot for that. Interesting results. Obviously 4xSGSS + widescreen is too much to chew, but in a single screen doesn't look too bad. Was it jerky or something? and would it be too much to ask to repeat the single screen test with no SLI?
May 7, 201115 yr I found a scenario where I exceeded 1.5 GB Vram: Las Vegas Megascenery + Aerosoft Las Vegas + FSDT KLAS + McPhat HD repaint on the CS 757. I got up to 1.6 - 1.7 GB Vram meaning that the Card was caching textures from System Ram and therefore stuttering like crazy.Also intriguing. What AA / AF settings was that please?
May 8, 201115 yr One more data point...on a single SHD (2560x1600) monitor, the highest VRAM usage I saw was in the very GPU-intensive SUPERVCAA_64X_4v12 FSAA mode at a FS Dreamteam airport in the RealAir Duke--it peaked at 1430MB, which is getting pretty close to using the full 1536 MB on the graphics card. With AA at 8xS and transparency AA at 2x Sparse-grid supersampling (still exceptionally good IQ at these settings), VRAM usage on the single big monitor was 800-900MB.So for mainstream (i.e. 1920x1200 resolution or less) single-monitor users, even with aggressive AA/AF settings I doubt the increased VRAM on a 3GB card would ever be in play in FSX.CheersBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO Bob Scott | President and CEO, AVSIM Inc ATP Gulfstream II-III-IV-V Sys1 (MSFS20+24/XPlane12+11): AMD 9800X3D, water 2x240mm, MSI MPG X670E Carbon, 64GB GSkill 6000/30, nVidia RTX4090FE Alienware AW3821DW 38" 21:9 GSync, 2x4TB Crucial T705 PCIe5 + 2x2TB Samsung 990 SSD, EVGA 1000P2 PSU, 12.9" iPad Pro Thrustmaster TCA Boeing Yoke, TCA Airbus Sidestick, Twin TCA Airbus Throttle quads, PFC Cirrus Pedals, Coolermaster HAF932 case Sys2 (P3Dv5/v4): i9-13900KS, water 2x360mm, ASUS Z790 Hero, 32GB GSkill 7800MHz CAS36, ASUS RTX4090 Samsung 55" JS8500 4K TV@60Hz, 3x 2TB WD SN850X 1x 4TB Crucial P3 M.2 NVME SSD, EVGA 1600T2 PSU Fiber link to Yamaha RX-V467 Home Theater Receiver, Polk/Klipsch 6" bookshelf speakers, Polk 12" subwoofer, 12.9" iPad Pro PFC yoke/throttle quad/pedals with custom Hall sensor retrofit, Thermaltake View 71 case, Stream Deck XL button box Sys3 (DCS/P3Dv4/ATS/ETS): AMD 7800X3D, MSI MPG X870E Carbon, Noctua NH-D15S, 64GB GSkill 6000/30, EVGA RTX3090 Alienware AW3420DW 34" 21:9 GSync, Corsair HX1000i PSU, 4TB Crucial T705 PCIe5 + 2TB Samsung 970Evo Plus, TM TCA Officer Pack, Saitek combat pedals, TM Warthog, TM RS300 FF wheel/pedals, Coolermaster HAF XB case
May 8, 201115 yr Also intriguing. What AA / AF settings was that please?NickN's setting for AA and Anisotropic AF.
May 8, 201115 yr Author What about if your running a TH2Go system, where the resolution is coming out at 5000x1000 (or something like that)? I would think that in that case you would be well over 1534 no? I don't have and have never used TH2Go, but am hoping to get one on the upcoming build so want to be well prepared.Cheers,Kael Kael Oswald 9950X3D/ 64GB DDR5 6200 @ CL30 / Custom Water Loop / RTX 5090 / 3 x 48" LG C4 OLEDs

The fact it that if you pile on enough addons and high def repaints(these really send up the V-ram), then yeah you could hit the 1.5 GB limit.
