Here is how to enable REBAR on non whitelisted apps/games

Made own thread for more visibility.

1 - Download Nvidia Inspector. Probably at least version 2.3 ideal.
2 - In Nvidia Inspector, look for the icon that kind of looks like a hammer 2nd from the right, if you hover over it, it says "Show unknown setting from Nvidia Predefined Profiles", Activate it.
3 - Now if you browse any game in Nvidia Inspector in the Unknown flags at bottom, look for the following line.
0x000F00BA (17 profiles)
and
0x000F00BB (17 profiles)

For games that are whitelisted these flags will probably be already enabled, for other games the value will be 0x00000000. You can flip it to 0x00000001.

Update - It has been brought to my attention there is a 3rd flag as detailed below to enable.

0x000F00FF - 0x0000000040000000

I checked a few games and the ones I checked with them enabled by Nvidia have both flipped on, so my suggestion if you trying this out is to flip both, click apply, then when you launch app/game REBAR should be on. Obviously this is use at your own risk type of thing.

I havent done any actual testing though as I cant use REBAR yet.

Is this an early April's fool joke or are you going on what is also said here

https://www.reddit.com/r/hoggit/comments/mhbphc/manually_enabling_rebar_support_for_dcs_with/

because the reddit link mentions 3 flags to change not 2.

which was in turn pinched from here

until someone comes up with a way to show its enabled in a game you dont really know 100% for sure and this so far has only been tried by one person in the DCS game who reckons it improved the game.

No joke, but thanks added the 3rd flag to OP.

I didnt get from reddit I got from guru3d where a few have been doing more testing.

It's turned off for some games because enabling rebar negatively affects performance.

So essentially overriding this is reducing your performance in those games.

Actually for the majority of games its off because they havent tested, this is why its useful, they clearly havent tested 10s of thousands of games.

A lot of games will probably never get tested, obscure ones, indie titles etc.

Sadly though we wont know which have been tested but crashed, or were slower vs not tested. So its a try and see. Nvidia will only list the games they have tested and see improvements.

I'm referring to post 1.



I don't see the 3rd flag values ("0x000F00FF - 0x0000000040000000") in non-supported games. The flag is blank there. So i just have to copy and paste "0x000F00FF - 0x0000000040000000" ?

What do i have to do with the 3rd flag?

its a pulldown, there is only 2 possible options. The second option will be the 0x0000000040000000 value.

Did you make sure to click on the icon I mentioned to make the flags visible?

Ahh yeah you cant just select default again, another method aside from entering all 0s is you can reset the profile to defaults (and then reapply any other customisations that may have been in place).

Hopefully a newer inspector gets released which makes this easier.

Nvidia just should add a reBar setting for the NVCP.

I already requested this and a guy who seems to close to the dev team said no chance of it happening. The thread I made on the nvidia forum also didnt get a single reply so disappeared into the void.
