Hello everyone,
I want to ask you something about the nVidia DSR Factors
Let’s say, I test it with RTX 4090 on 4k resolution
If I enable 4x in the DSR Factors ( in menu game, as well, 7680 x 4320 ) which is 8k
Is this test, real ? Does it simulate 7680 x 4320 pixels ?
I asked, because, right now I play at 4k ( 55 inches ) RTX 3090
I ordered the RTX 4090 ( Gigabyte, OC ) but I do not want to purchase the 65 inches 8k, before I have an idea about the RTX 4090 performance at 8k.
When I get the 4090, I’ll try all my games, with the 4k display I have right now ( sim racing and flight simulators, only ) with the DSR Factors 4x
If I get 30 fps, average, I’m okay with that.
Any advices are welcome, thank you
Yes, it will load the GPU the same way as driving the extra pixels. Although, I believe DSR 4.0 at 4k would be the equivalent of 16k.
I used the same method to approximate how my “old” 3060ti would perform before upgrading my 1920x1080 monitor to the 5120x1440 Samsung G9, (using resolution combos that would get me close to the 7.3-ish million pixels the GPU would have to render with the new monitor). You can use DSR, Render scaling, or a combination of both to set the resolution (pixel count) you want to test.
In my case, the predicted FPS was within a percent or two, so go for it, your test will get you very close to what you can expect with the new screen.
FWIW, it’s not “simulating” the higher resolution. When you set DSR or Render Scale to 8k, as in your example, the game should be actually rendering in 8k. I used to use DSR with my 1080p monitor, rendering in a much higher resolution, to load my 3060ti enough to get out of the mainthread limited condition that caused stutters. Now that DX12 works for me, I have swapped the 3060ti for a 3080, and the sim has been heavily massaged since those days, being mainthread limited is not nearly as much of a concern.

Lol just make sure you buy a hdmi cable that will support the additional bandwidth. It might cost as much as the TV 
If a cable, hdmi 2.1 is expensive, you shouldn’t play MSFS 2020
lol
It’s too expensive for you
