Those of you who use AMDs VSR with 120+ Hz monitors

[cusideabelincoln]

I'm trying to compare the feature set of my system against others who have a 280x, 285, or 290 video card.

Now the 280x doesn't officially support VSR, but I downloaded tweaked drivers that enable it for me. It does work in the few games I've tested. However, I have a 144 Hz 1080p monitor and I am connected via dual link DVI.

At 1080p I can run 144 Hz just fine. But if I select 1440p for Virtual Super Resolution, my refresh rate is limited to just 100 Hz. Is this a limit with my drivers? Is this a limit with DVI? Is this a limit my monitor? Since the video card is downscaling the 1440p resolution to 1080p before sending that signal to my monitor, I assumed I would be able to run my games at 144 Hz, but like I said that doesn't appear to be the case. Perhaps it's possible VSR isn't really working, and my monitor is doing the scaling? I'd like some more info before I begin my testing.

Oh, and for those who do use VSR with a 290 card on a 1080p monitor, what is the highest resolution you can select? And does text get smaller when you guys use VSR?

it's the same with nVidia's DSR, i believe you are limited by DVI's bandwidth. the higher the resolution goes, the lower the refresh rate.

AMD is using the inbuild display controller to rescale the image. So you are limited by this.

nVidia is using a software approach. So there literally doesnt exist a limit.

There may be no hardware limit, but there certainly is a limit. Just because its software doesn't mean its infinite.

I dont know if there is a software limit. But you can increase the factor for each side in the registry.

And the guy who did nvInspector wrote a tool which allows you to increase the factor above 4x. For example you can use 5x5 for each side which results in 9600x5400 (1920*1080).

THat's not true -- can use 4k at 120hz!

 

[Squeetard]

I bet you are using display port and not DVI.

 

[SirPauly]

DVI for me.
