Nvidia Rebar Settings

[MajorMagee]

If you what to try out using Rebar there are three settings you'll need to activate using Nvidia Profile Inspector.

In the System Memory and Compute section you'll find:

rbar - Enable  For this, switch from the default Disabled to Enabled

rBar - Options  For this set to 0x00000001 (Returnal, Red Dead Redemption 2)

rBar - Size Limits  For this set to 1GB

I found that setting a larger memory size led to stuttering on my system.

The latest 616.56 driver is supposed to allow accessing this option from within the Nvidia App, but it still doesn't show up there for me yet.

I have it enebed is a day one, did you noticed any benefits?

Nothing measurable.

I just tried moving the memory size limit up to 2GB without any stuttering. Still holding at max FPS for my Gsync Monitor, even down low flying over cities.
