You Need To Turn Resizable Bar On! – 12 Game Benchmark

How much does Resizable Bar change performance?

I have 12 games to benchmark here. All of these games will be tested in 1080p, with overall comparisons given at the end.

I will compare when ReBar is Off and On, which is set through the Nvidia Profile Inspector forced for all games through the global settings.

  • DLSS is off
  • CPU and GPU are stock, with no overclock
  • Games tested in Fullscreen
  • Vsync is off
  • Nvidia Low Latency is off, but if it’s turned on, like in Valorant, I will let you know on the graph.
  • Frame rate uncapped
  • Ray Tracing is off 
  • All Games Benchmarked on a 3-game Average
  • Nvidia Driver Tested on: 551.23 – 24/01/2024 (DD/MM/YY)

Here is the video of ReBar On v Off Benchmarks:

Correction: at 6:55, I was supposed to say A Plague Tale Requiem, being a 21*% difference for Average FPS.

Graphs of the Games – Hover to see the Names of Games:


A Plague Tale: Requiem

We have A Plague Tale Requiem for the first game on Ultra settings.
There was a significant uplift in performance for this game, going from 78.93fps to 100.37fps when Rebar is on. This was a 27% increase in average fps. The 1% lows fell slightly, with a -9.31% percentage difference between rebar on and off.

Assassin’s Creed Valhalla

Next up is Assassins Creed Valhalla on the Ultra preset. There is not too much of a difference here, with the uplift of Average FPS only being 1.55%. On the bright side, the 1% lows were much better at a 16.94% increase with rebar on, and the game felt much smoother. 


Cyberpunk 2077 has something similar, with the game feeling much smoother with Rebar on. There was a small increase in average fps of 8.01%, but 1% lows had a major improvement, going from 35.8fps to 64.5fps, which is an 80.17% increase. Quite happy with that result.

Forza Horizon 5

Next up is Forza Horizon 5 on Ultra settings. This was a bit surprising, with both the 1% lows and the average FPS having decent uplifts as a whole. The Average FPS increased by 14.27% and 1% lows, having a solid uplift of 61.26%. I do want to see how this game scales as well at 1440p.


GTA 5 is one of the titles where Rebar Off was actually better than On. There was a 6.36% decrease in performance for average FPS and a reduction of -13.04% in 1% lows. I’m not too sure what happened with this one.

Hogwarts Legacy

Hogwarts Legacy is up next and this troublesome title has a slight increase in average fps being 16.30% and 1% lows only improved by 6.53%. Unfortunately, the smoothness of Hogwarts was still about the same and didn’t improve too much for the runs I did.

Horizon Zero Dawn

Horizon Zero Dawn was up on the test It had a nice improvement overall; the game was much smoother, and the 1% lows increased by 59.11%, which was quite hefty. The average FPS had a solid increase as well, going from 111.90fps to 127.90fps, which is a difference of 16fps.

League of Legends (ARAM)

Our first Esport Title is League of Legends and I didn’t really expect much out of this game for improvement with rebar. The 1% lows were better with rebar by 15.54% and only a minor improvement with the average FPS being a 5.08% increase.

Ratchet and Clank Rift Apart

Ratchet and Clank Rift Apart is a title I really wanted to see with ReBar enabled. Unfortunately, it only helped slightly, but again, the 1% lows were at a 17.91% increase and helping the experience in the game. The average FPS disappointingly only was a 7.15% increase but I think we were reaching the maximum of what this system could output from the RTX 3070.

Shadow of the Tomb Raider (2018)

Shadow of the Tomb Raider, unfortunately, pretty much played out the same with Rebar on and off. There is only a slight increase in fps by 1.92%. If you can even call that an improvement, I don’t really think so. Game performed well in either case.

The Callisto Protocol

The Callisto Protocol on High settings honestly didn’t have much of an impact when Rebar was on for average FPS or 1% lows with both being only a 1.13% increase for average fps and 1.88% increase for 1% lows fps.


Now Valorant was surprising, being our 2nd esports title, I really wasn’t expecting much.
On Average, FPS Valorant improved by a solid 13.12% and the 1% lows at an increase of 23.43%, which was really nice. I guess in a game like Valorant more fps is technically better and I could feel the improvement in the Death Matches I played. On a side note, just as pure feeling playing with ReBar enabled in unrated and ranked games, I personally could not feel much of a difference, but this is just down to perception for myself.

Graphs of the Overall %Differences for Average FPS and Average 1% Lows:




Overall, there were some good results with Rebar on with significant improvements coming from A Plague Tale Requiem being a 21% difference for Average FPS. Notably, GTA 5 performed worse, and The Callisto Protocol, AC Valhalla, and Tomb Raider didn’t impact performance much. I think the 7% is decent overall from the 12 games for average FPS and with not many drawbacks in the game.

Again, on the 1% lows, we have a 7% difference, which is decent for helping stutter in these 12 games. Cyberpunk felt much smoother and had a 57% percentage difference when rebar was turned on. A Plague Tale Requiem and GTA 5 were worse off, and I didn’t expect Plague Tale’s 1% lows to fall here. Not a bad result overall.

Some Final Thoughts:

  • In essence, Resizable bar is a feature that is already on avaliable some systems, so you might as well take advantage. If its causing issues then you just have to turn it off again.
  • I want to try this again at 1440p to see how the scaling is overall and it would be interesting to see how the 8GB VRAM buffer is at 1440p, where we were already reaching the max of it some games with
  • You might need to update your BIOS to use ReBar, as my motherboard had the option turned on already, but it was showing as off on Windows.
  • At least in these twelve titles, Rebar didn’t hinder performance much, and only A Plague Tale Reqium and GTA V were worse off.
