Using Nvidia DSR to reduce CPU bottleneck?

[m0k]

So we all know that at lower resolutions a CPU can often be more crucial in gaming performance

ex. at 1080p a weaker cpu will struggle to keep up with a good gpu - in my case a Phenom X6 1090t running at 100% load , while my GTX 1060 6gb load is only at 40-60% (in BF1)

 

So i thought maybe if i could play games at a higher resolution, it should mean higher gpu usage? = higher fps??

And because i only own one 1080p monitor, and dont have the budget for a new one - i thought i could just increase the resolution using Nvidia's Dynamic Super Resolution to run games at higher DSR factors (and higher resolutions).

 

Now its currently really late and i have not had a chance to actually test this out - I was wondering if anyone else has .

 

And please feel free to tell me ahead of time if my hypothesis is critically flawed in any way

Cheers

Will report back on this thread once i get to test it out later in the week

You will most likely see higher GPU usage but your CPU usage will stay at 100% most of the time. Your FPS should not really change with DSR as long as you stay under 100% GPU usage.

So you wont remove the CPU bottleneck but you will increase the image quality a bit with no FPS hit... in theory.

In your case, the only way to remove the CPU bottleneck is just by introducing a GPU bottleneck. You may increase DSR by a lot to see which situation is better.

It does reduce CPU bottleneck, but by increasing graphics quality, not increasing frame rates.

Increasing the resolution increases the amount of work that the GPU needs to do for each frame. The GPU usage goes up because each frame requires more GPU usage to make, not because you're making more frames.

Higher GPU usage but not higher fps.

Will not increase FPS but it will look nicer and in most cases wont decrease FPS below what it is now unless you set it to something crazy like 4k or 8k! :3

 

Edit: Reduce, lights, shaders, shadows & physics settings may improve FPS tough.

FPS can only go down from a point of being restricted by the CPU.  The best you can do is to make that 30 FPS the absolute best looking 30 FPS.
