ReBar On vs Off - Texture resolution Ultra vs Medium - Vram usage tests (not fully finished, it is to give you guys an idea what to do for saving more Vram)
Summary
1080p DLSS Quality
ReBar Off - Medium textures - Cockpit - 3.529gb Link
ReBar Off - Medium textures - Outside - 3.468gb Link
ReBar On - Medium textures - Cockpit - 4.514gb Link
ReBar On - Medium textures - Outside - 4.444gb Link
ReBar Off - Ultra textures - Cockpit - 6.059gb Link
ReBar Off - Ultra textures - Outside - 5.904gb Link
ReBar On - Ultra textures - Cockpit - 7.345gb Link
ReBar On - Ultra textures - Outside - 6.966gb Link
1440p DLSS Quality
ReBar Off - Medium textures - Cockpit - 3.895gb Link
ReBar Off - Medium textures - Outside - 3.910gb Link
ReBar Off - Ultra textures - Cockpit - 6.988gb Link
ReBar Off - Ultra textures - Outside - 6.790gb Link
(Rebar On results for 1440p screen captures failed it seems, but add around 1000-1300mb to ReBar off results, here is ReBar On - Medium textures - Cockpit - 5030gb Link Sorry in pains, i will test and add them when i feel ok…)
Texture Resolution Medium and Low gives the most Vram usage savings and texture resolution does not affect aerial images as far as i know. I couldn’t see any difference Ultra vs Medium on cockpit, airplane or ground. On Low textures, i saw some quality loss on some cockpit textures like seats and airport ground. Here are some comparisons
Example from above 1080p results (ultra texture results includes Raytraced Shadows, around 300mb extra usage for X cub):
ReBar Off - Medium textures - Cockpit - 3.529gb
ReBar Off - Ultra textures - Cockpit - 6.059gb
Maximum saving comes from Texture resolution Medium/Low 2.5-3.5gb+, ReBar Disabled 1.0-1.4gb+, Raytraced Shadows off 300-400mb+, detailed ground textures 200-300mb+. Big Airports, big airplanes may produce higher results. LICJ Gate110 X cub used for tests. 12:04 ingame time, clear skies. DLSS helps a bit but not much. Nvidia 566.14 driver used. Latest driver and new game profile(ReBar profile) may give different results. Feel free to test for your systems. 7800x3D RTX4070 12gb 2x16gb Win11 24H2. Need to rest peace.
All texture Ultra vs Medium tests done by Restarting Sim fully. Same for ReBar. Do not change any settings while in game and test them. 1080p tests on Samsung 1080p 60hz TV, 1440p tests on LG C1 1440p 120hz Gsync Vsync.
Here are some more ReBar Msfs2024 informations
Edit1: Off Screen Terrain Pre-Caching > Ultra vs Medium - 4.050gb vs 3.529gb
Edit2: 310.3.0 - DLSS Performance > Post 2560x1440 > Render 1280x720 - Preset K test (ignore stuttering, OBS + Gsync/Reflex issue) (Vram usage gain minimal 100-120mb vs previous dll, can be higher on 4k)(improvements for 5000 series MFG)

How to check ReBar Requirements
I keep reading people saying that they don’t see any differences when enabling/disabling ReBar. You can check ReBar Requirements with GPU-z as seen in this picture.
