DSR rocks...give it a shot

I'm not going to explain dsr (supersampling) but for those nvidia users that can use it, I ask you to try it on an older game.

Setup L4D2 yesterday running at 4k, rendered on a 1080p screen, and with aliasing off.

Not a single jaggie, and somehow it LOOKS so much better. Sharper...with many more details.

Anywhos...just wanted to suggest those of you who can, should try it out. It breathes life into older games that you computer can crush numbers wise (at 4k I was getting 90+fps with one of my 970's alone)

One of your 970's... Why do you have two 970's and only a 1920x1080 display?

I was so excited about it too before I realized that the 400 series are incapable of handling it (just as I was about to download the drivers). Time to upgrade.

What is the performance impact? I have a 770 would I reasonably be able to do 4K without taking a tremendous performance hit? Guess I could test later today myself, but since I am work atm figured I would ask :P

Old games yes, not new ones and definitely not on high-max graphics

Ok yeah...that's what I figured. When I first head about it I thought this was some upscale magic thing that wouldn't have much impact...I watched a video of it though and it showed them setting the game's graphics resolution option to 4K had the feeling it wouldn't be feasible for new games.

But hey, for old games guess it still would be neat.

For example, with my 770, the GeForce Experience is suggesting me to run Dota 2 at 2715x1527.

Yea, DSR is great, I use it in just about every game. Much preferable to MSAA.

The reduction in jaggies is not worth the added input lag and lack of smoothness. Any kind of super sampling post processing is not good for the feel of the game. I would not recommend using DSR. Just run at the native resolution of your monitor.

I do not detect any added input lag from DSR other than whatever input lag you get from the FPS hit. The image quality of DSR + 2x MSAA looks a lot better than non-DSR 8x MSAA.

I get my 970 on tues or wed, will definitely be trying it out soon

Anti-aliasing in general adds input lag. Try playing an FPS game with Vsync on (yes I know it adds input lag, but I can't stand tearing) without DSR or MSAA. Now, try playing the game again with the same constant Vsynced framerate with DSR or high MSAA. You will notice a significant increase in input lag. The higher the MSAA or DSR, the more input lag. You can even try this with BF4 and it's built in resolution scale. You will get the same results. I am running 970 SLI, btw. I am able to run most games at the higher DSR resolutions without dropping below Vsync.

I did the monitor tweak before this. Not worth the FPS for a less jaggy filled game. Maybe when these GPU's can do 4k at 60 FPS I would consider it.

I never use Vsync purely because it lags. DSR with no Vsync has no detectable added input lag. My setup definitely doesn't exceed 60 FPS when I add AA on top of DSR. If you cranked AA you really shouldn't have a problem keeping it around 60 except in older titles.

^ this right here. I noticed a lot of extra input lag with it on. Also added more blur to the image (in some games) so the image lost its clearness and sharpness. I'm using a 680gtx so people using the newer 970 or 980 gtx probably won't notice as much lag as I did.

I do like this DSR option though, its great for taking really high res screenshots if you only have a 1080p monitor. But i find games look better and sharper using just 1080p native res on my monitor mixed with SMAA with sweetfx and maybe 2x AA if the game allows that ontop of the SMAA... usually just SMAA is all i need.

I couldn't get DSR looking smooth unless running at the max res (3840x2160). All the other resolutions I had to apply about 15-20% DSR smoothing to make them look decent without nasty edges and artifacts... which added the problem of causing too much image blur making it look crappy and making 1080p look much better to stick with.

Future driver updates probably will refine this though i hope and fix it more. Overall this is awesome addition to nvidia cards and for games that don't work with AA or supersampling this is an additional option to smooth things up if your card can handle it. Most new games i can't run this on my 680gtx, but some older games im looking forward to testing out to see how this can help them look.

Tried 3840x2160 on Civ 5 and it really was hard on the eyes, all the text was tiny and blurred so 1080p is where im sticking on this game.

Tried it on TERA at 3840x2160 and it looked amazing, but fps dropped to 30-40 so i won't be playing it at that. Also had a lot of noticeable input lag from my mouse movement.

Tried 3840x2160 on NFS Most Wanted 2005 version, but the game still looked better at 1080p with 4xMSAA and 8x Supersampling and had no input lag with that, but lots of lag with DSR.

Saints Row 4 at 3840x2160, looked smooth even got 45 fps but there was a lot of stuttering and it wasn't fun to move around with, the game had a lot of noticeable input lag and screen tearing.

Pretty much all the games went on like this, not enjoyable to play at for minor edge reduction. Mild AA takes off edges just as well with almost no performance hit. And the fact you can use SMAA most of the time with AA with nearly no hit makes DSR not really worth playing a game with for me.

I'll probably upgrade my video card next year sometime or even this year if I found a 970 or 980 cheap... so hopefully DSR is more practical on those.

That's the next purchase I need...I'm debating waiting for a cheaper gsync monitor...I loathe tearing so much, but I also want qhd and 120hz. The rog swift is just a bit out of reach financially for a month or two.

Older games than you can crunch easily really benefit, though some games the interface scales a little weird (Saints Row 4 for example...icons are a little close to the middle, but not bad).

I haven't noticed ANY kind of "lag" with DSR yet, though I've only tried it on a few games. L4D2, SR4, and Titanfall (crush it max settings rendered @ 4k, and still pushing well over 60fps with no drops below)

What games are you guys playing that give you lag? I haven't perceived any at all, whatsoever.

You could already do this in the Nvidia control panel. Just set a custom resolution and save it, then select that resolution in the game menu.

My GTX780 was easily able to render Dishonored at 4k down scaled to 1080p and it looked significantly better than just running it at 1080.
