Looks good, in some games the impact on the fps is lower than the DSR factor. Overall it looks quite linear Edit: Hitman added
You're welcome. Tested Hard Reset. 2880x1800 downsampled to 1920x1200, in-game FXAA, Ultra: Driver/normal downsampling 2880x1800 = 193.3fps https://farm6.staticflickr.com/5614/14988928883_c4fbd9ab36_o.jpg DSR 2.25x default smoothness 2880x1800 = 188.4fps https://farm6.staticflickr.com/5612/15609897882_1dc28fa9c2_o.jpg GeDoSaTo bicubic downsample 2880x1800 = 187.3 https://farm4.staticflickr.com/3938/15609065985_459d890272_o.jpg
Nice screens man !!! Just what I expected really, there is no massive performance hit of using DSR vs Driver Downsampling, or even GeDoSaTo to the same resolution. Its a couple of FPS here and there (as our tests have shown)
Thanks, I got the same card (from MSI). Edit HOLY CRAP, I tried DSR Factor 4x in Dota 2 and FPS is still above 40? Link (for the screen shot) -> http://cloud-4.steampowered.com/ugc/35227289382681530/15B6C7587673CB154C9B40AD740D48C3DDDD50F7/
Try running it in 1440p, do you get stuttering? Mine runs smooth at 4k but I get stuttering at 1440p.
This is strange because I've changed the filter setting from 0 all the way to 100% and saw very little change in FPS. For example Arkham Origins @ 4.00x DSR, filter at 0% Min 49 Max 112 Avg 81 With the filter at 100% Min 51 Max 115 Avg 81 Essentially no change. In game AA is off, all other settings on max. I lose about 10 FPS or ~10% versus running the highest in game TXAA setting.
I'm using a 2560 x 1440 monitor. Whenever I increase the resolution in game through DSR in Dota2, everything just looks weird at 1.2x (2804 x 1577), same if I go 1.5x. The text is the most obvious part, it's just not as crisp as running native resolution. Most stuff just looks "out of sync" if that makes sense. I feel the performance hit if I go higher too, so far I just haven't seen the benefit from this feature.
Tried this with my stock GTX 580 Lightning EX. Tried various old and new games, was generally playable but very stuttery for me using 4k and max settings except for AA (no AA and off at NV CP). AF was x8 in NV CP. Was getting like 20-25 fps in Diablo 3 in town, and lol 5-10 fps in heavy battles. All Crysis games ran very poorly (something like 10-20 fps). Heroes VI ran ok-ish, 20-35 fps. Might and Magic X ran very badly, like Crysis games. But what gets to me is the text. Its barely readable and blurry. I tried the smoothness slider but that doesn't seem to fix this issue. Enabling FXAA seems to fix it in Diablo 3 though. Haven't tried other DSR like 2x, etc, settings though. Might try 25x14 later.
I tested my friends 970, and compared to my 670, in exactly the same system, the 970 gives me WAY more performance for every level of DSR. Borderlands 2 is 110fps at 1.2x DSR on the 970 And 35fps at 1.2x DSR on the gtx 670 When Running Native resolution (2560x1440) the 970 gives me an average of 128fps and the gtx 670 84fps. This is with ultra physx. This is with both cards being swapped out in the same system. So yeah, the gtx 970 or 980 might be nearly twice as fast when it comes to native rendering, but they are four times as fast when it comes to DSR.
Flawed. We need to know what resolution DSR 1.2x equates to in your test. We then need to know how the 670 performed at this resolution with bilinear driver downsaming. Then we can make conclusions about the 670's ability to handle DSR. Idk if performance scaling as resolution increases is completley linear, but it could just be that the 670 is ok for this game at 1440p, but due to memory/bus/bandwidth/pixel fill rate etc it just struggles disproportionatley in general when the resolution goes higher than this.
My native resolution is 2560x1440, you are right it was flawed, the benchmark did not have enough information. I was too busy trying to play other games on the 970 and testing out my friends gsync monitor. I want a gsync monitor now. It also seems to smooth out low-fps sli frames. Which barely anyone has talked about.
So..so many things have changed with newer drivers,meaning this thread is misleading and should be in a graveyard IMHO.. DSR is great addition for gaming and with the smoothness(sharpness) percentage setting you can have whatever you want now.
