I decided to test the new Resizable BAR setting out of curiosity - AUTO (Enabled) vs Disabled and see what impact it has on MSFS 2024.
MSFS 2024 FENIX A321, a 20-minute test flight from YMHB to YMLT.
4K TAA.
Lower = better
For GPUs where VRAM capacity isn’t a limiting factor, as we can see, Resizable BAR Enabled gives us, among other things, +22.5% more FPS and lower frametimes, so it’s all benefits.
