Does DSR do anything?

  • Let's say I want to change DSR to 4k in-game. Do I also have to set DSR to the same for my PC itself as well? My PC runs in normal 1080p, so will DSR set to 4k in-game work by itself, or do they both need to match to take effect. I ask this, because I recall trying this before, and saw absolutely NO difference.

    This question is part of my never-ending quest to get the ugly jaggies under control. Did a lot of research today, and was stunned to find that AA methods for DX11 is a universal issue, NOT just GTAV itself. Apparently improving AA methods have been kicked to the curb since DX10.

    I think my issue is more noticeable because of how close I sit to a 40" monitor, so the jaggies really stand out. All methods between in-game settings, nVidia control panel, SMAA in sweetFX, has produced absolutely no positive results. I have now only to look at turning MSAA support on in the enblocal.ini, and after that, the only thing left is to drop back to DX 10.1 so I can use SGSSAA from nVidia Inspector profile.

  • @eshenk You have to enable the DSR options in the Nvidia Control Panel, called DSR - Factors and the multipliers in there tell the games what resolutions can be used.

    If you enable all the options in that setting, you will get more resolutions available in-game, above your native resolution. What it effectively does, is render to a larger rendertarget, and then downscale it to your native resolution. It's like getting a 4K digital photo and displaying it on a 1920x1080 resolution screen.

    The idea is that the downscaling is supposed to remove jagged edges, much like shrinking an image does in Photoshop.

    All I have found with it is a) It kills my FPS and b) It completely screws up the icon positions on my dual monitor setup. Maybe that's because I keep my desktop at 1920x1200 and tried running higher DSR factors, I don't know. For me it gave nothing back that was positive.

  • The desktop icon issue seems to occur on single monitors as well going off this thread https://forums.geforce.com/default/topic/903793/desktop-icon-positions-not-remembered-when-using-dsr-resolution/

    There does seem to be a solution at the bottom which might work... will try it in Windows 10 as I don't care where those icons end up. :D

  • @LeeC2202 I used DSR back when I had a 1920x1080 monitor, all icons come back to their rightful places when I close the game.
    But you have a dual monitor setup, so all icons end up in a single display even after you close the game, am I right?

  • @V4D3R Yep but as you can see from that thread, unless you set your desktop to the same DSR resolution, it happens on single monitors as well.

    I have just tried it in Windows 10 and setting the desktop to the same res works, but you either get text so small you can't read it and a normal mouse cursor, or normal text and a huge mouse cursor.

  • @LeeC2202 Do your monitors have the same resolution?

  • @V4D3R Yeah, they're an identical pair of 1920x1200 monitors.

  • @LeeC2202 One of mine is 2160p and the other is 1080p. When I used the 1080p one as my main display, I used my older 1600x900 display with it. When I used DSR, both monitors' resolution changed. Is that normal?

  • @V4D3R Both of mine change when I use it, so I suspect so.

  • @LeeC2202 Thanks for the confirmation. :thumbsup_tone1:

  • @V4D3R I get the same problem when I play games at lower than normal res. Everything gets shifted about and some of my left monitor ends up on my right monitor.

    Desktop wise that is... not the actual game.

  • @LeeC2202 @V4D3R I have 2 screens too, one is an 1080p TV and the other one is an bit older 1440x900 and when I use DSR, it only changes the resolution of my main screen. The icons get thrown all over my screen but gets back when I change to 1080p again

  • Hell yea DSR improves the native picture quality and got rid of all my jaggies. It costs some performance though

  • DSR looks good imo, I keep between 15 to 20% smoothness & use 4x for 3840x2160 on a 1920x1080 screen. I dont have problems with desktop icons resizing. That might be an issue on 1200p screens.

    Sgssaa works on DX11 in gtaV since r_376 driver, but initially it only worked in dx10 & dx10.1

  • @turtlevan said in Does DSR do anything?:

    I dont have problems with desktop icons resizing. That might be an issue on 1200p screens.

    They don't resize, they move to their default locations stacked at the left edge of the screen. Many users report the same problem with 1080p displays, so it's not unique to 1200p.

  • @turtlevan I don't see sgssaa as an option in the nVidia profile inspector.
