I'm having a true first world problem. I'm lucky enough to own a 32" UltraHD screen (Asus PQ321QE) and a 30" 1600p screen (Dell 3007 WFP-HC). As you are no doubt aware, Nvidia have brought out DSR, which can actually allow me to render at 5120x3200 and then downscale to 2560x1600. And I can't make up my mind which I prefer! UltraHD advantages: Less performance demanding* (never thought I'd write that!) Fine pixel pitch allows fine details to really come out Beautiful colours UltraHD disadvantages: Still can notice 'shimmering' antialiasing effect when in motion Very slight lag (not enough for me to care) Can get 'split' screen issues at low framerates 3200p advantages: No 'shimmering' antialiasing effect Holy crap! I'm rendering at 3200p! More 'stable' than UltraHD Game doesn't support AA? Now it does! No lag 3200p disadvantages: Lower pixel density means you can see individual pixels when concentrating Using it means my nice UltraHD monitor goes to waste Colours not quite as good as UltraHD monitor (though still damn good!) More performance demanding* Stupidly small writing / HUD scaling *For now, don't worry about performance issues - I have a solution to that. Of course, if Nvidia would just release 8K downscaling, this would be a much easier dilemma to solve. Let me know your thoughts peeps!
Yeah, i love 4x downsampling aswell... having the game render 4 pixels pr actual pixel on your monitor completely removes aliasing. But id still go for the extra detail the 4k monitor provides
I'm thinking I agree with you. I've taken some comparative images below but only those with an UltraHD screen or above will be able to tell the difference - click on them for the high res versions. 4K Image 1 3200p Image 1 (cropped to 2880p) 4K Image 1 3200p Image 2 (cropped to 2880p) The fencing is slightly better in the 3200p shots, but only the UltraHD monitor can show the difference (the signs are also ever so slightly sharper). The images appear the same on a 1600p screen. However, as mentioned, a moving image on the 1600p doesn't show antialiasing artifacts, presumably for the very reason that it is impossible to tell the static images apart on a 1600p screen. Grr!
Yeah, the 4 pixels rendered pr 1 shown pixel is just amazing for AA, but its a very high performance cost, for not THAT big a visual difference imo. Anyways using nvidia's control panel fxaa should more or less completely eliminate the shimmering on the UHD monitor, without giving noticable blur But else you could still use the 4k monitor together with DSR 1.5 for instance - would give you close to the same rendering resolution as on the 1600p screen using dsr 4.0 , but with a screen that could better show the difference
I would love to but I can't get DSR to activate when I have my UltraHD screen attached. I know there are other methods but they can only be used on DX9 games. Hmm, I shall activate FXAA on top of any AA applied and see if it makes things better.
Really? Cause you can boost res above 4k with dsr, as you are doing yourself aswell with 5k on your 1600p screen. Applying the nvidia control panel fxaa SHOULD remove most if not all shimmering when using it on a native 4k screen
Well, it's like this: I have one rig with the 1600p screen, which allows me to activate DSR. On my main rig with the UltraHD monitor attached, the DSR option is removed from the Nvidia control panel. However, this may be due to the fact that I also have a secondary screen attached - this is necessary as the UltraHD monitor uses Displayport 1.2 and therefore won't 'boot' until Windows is at the log in screen. Does anyone reading have a single UltraHD monitor or screen that uses Displayport 1.3 or HDMI 2.0? Does this solve the problem of having to have a secondary monitor attached?
Well, the login screen to Windows is the first time you really need to use the monitor, unless youre doing bios setup, no? If so, id simply pull off that secondary screen, and see if you can make it Work with dsr on that 4k screen
Yeah, thats a tough one then :/ Did you try forcing fxaa through nvidia control panel on the 4k screen ?
