ReBar causing VRAM overusage and decreases available VRAM amount in MSFS 2024

I went from, say 12gb used/13gb available to 11gb used/14gb available in many/most scenarios.

I observe something similar - about 1GB less VRAM usage when RBAR is off.

Resizable BAR is not the reason for high VRAM usage in MSFS 2024. Disabling it may reduce VRAM usage by about 0.5–1 GB (I tested MSFS 2024 with RBAR on and off), but that’s about it. It can make sense to turn it off if your GPU has limited VRAM. On cards like the RTX 4090/5090, however, there’s more than enough memory, so this setting really isn’t something to worry about.
