Nvidia Resizable BAR On v Off Benchmarked - You are missing out!

[@beezito]

Notes: Correction: at 6:55, I was supposed to say A Plague Tale Requiem, being a 21*% difference for Average FPS. I made a tutorial on how to enable ReBar for an Nvidia GPU (30 series and above) Check it out: kzbin.info/www/bejne/fnbboXqJq76Hg80 :D

From my testing it doesn't really make much of a difference in fps, but with Rebar it uses 600MB more VRAM in Cyberpunk 2077 compared to off. In VRAM constrained situations like path tracing it hurts performance even more so I have it disabled on my 3070.

[@beezito]

That's fair man bit of an odd thing still 😕

[@mikymouse7525]

@desmond3245 You are right. The differences are minor. I don't know how he obtained these huge differences in the tests.

By having a bigger shared space between the cpu and gpu gives it an almost auto range of good performance

[@EinSwitzer]

Hardware reserved is normally what the gpus would have to shared paper space to create rendering

Resizable bar on has always been my choice with my Nvidia gpu. Worked great on my old rtx 3050ti/Ryzen 5600H laptop since it was only 4gb vram but my system has 32gb so definitely gain almost 30% in some games. Now I have have a laptop with RTX 4060/ryzen 7940HS and I’m sure I’m getting gains since it uses faster ddr5 system ram. Maybe I can do my own tests.

[@beezito]

Nice :D lmk how the testing goes on your new build sounds interesting with that CPU 😁

[@shittyboxBuilds]

@@beezitoyes I’ll try it soon I just try to run a Linux distro and it crapped out so I’ll maybe get some info next windows instalwr

Physicist based games and ray tracing

Then they over extend and over interpret

[@mikymouse7525]

If you want to test correctly, you must install windows in compatible mode for resizable BAR OFF and in UEFI mode for resizable BAR ON. The results will surprise you. I can give you an example: Superposition R-BAR ON -> 21655, R-Bar OF -> 22065.

@@mikymouse7525 That's really interesting man :D. When ur talking about windows in compatible mode are you talking about CSM being disabled? Yea U have to have a gpt drive. I found gta v wasn't that great with rebar on and plague tale wasn't a very nice experience either. What are the specs of ur PC? :)

@@mikymouse7525 ;). ReBar is a bit odd xD, I'll follow this video up with a 1440p one and ray tracing in the same video. Some of my 1% lows are not good with 1080p rebar off, and I even found this true with r7 3700x, which I used previously. Sometimes it's system dependent :/. Will be doing another follow-up video hopefully, you will see it in the next two weeks or so. Appreciate the comment, though, as well :D Have a good day! :)

[@chris-gw2rt]

make a tut on how to enable

[@beezito]

Yea sure it's really easy haha :D

[@YTKeepsDeletingAllMyComments]

Depends on the CPU manufacturer and the motherboard. In my Ryzen 5700x system with an ASRock motherboard it isn't even called Rebar.

[@skyunn]

How to enable it?

[@beezito]

Using the NVIDIA profile inspector make sure you turn it on in the bios 😁. I'll make a tutorial for Monday on turning it on ;)

[@4head_high57]

​@@skyunnspam the delete key during startup to head into your motherboards bios. Find the rebar setting and enable it
