RESIZABLE BAR

[thegamingplumber]

turn it off in your bios right away if you're experiencing crashes. also fixes the framerate

Rebar is enabled and configured at the platform level. The GPU driver can't even directly reprogram the BAR, it has to ask Windows to do it.

You can see the difference in memory mapping yourself by going to device manager -> GPU -> Resources and comparing memory mapping with ReBAR enabled and disabled in the bios.
What the Nvidia profiles are telling you is how the driver wants the BAR to be configured.

Really?

ReBAR is the ability to reprogram the base address registers at runtime. With ReBAR off, they are configured (256mb typically) by the system firmware and locked at boot.

ReBAR on allows the registers to be reprogramed by the OS and enables all of the memory mapping required for it to function. The GPU driver is still ultimately responsible for deciding how much of this IO gets exposed.

ReBAR just enables the functionality it is still up to the GPU driver to make use of it.

You are absolutely clueless. rBar have to be explicitly enabled in the nVidia driver for the game.
Just stop posting.
