Q: Dynamic Super Resolution Factors.

[Facarwi]

Hi everyone.

 

So I have been playing around with DSR, I think I have a pretty good grasp on what it is, and how it works. It renders a game at a higher resolution then scales it back down to the native resolution (downsampling). The "Smoothness" setting adjusts the intensity of the Gaussian filter applied to the DSR image, it does this to offset artifacts from having to calculate how to blend/fit a larger number of pixels into a smaller number of pixels.

 

Okay I get all of that, from what I read X4 is the best setting.... What about newer games where performance becomes the limiting factor? For instance I am playing MGSV atm, which is void of any AA methods apart from FXAA, and forcing AA methods through drivers has no effect. DSR is a highly recommend method to improve the imagine quality but when X4 is not possible (only have a 970) what are the best factors to use? I have googled as much as possible and the two most common recommendations is using either 1.78 or 2.25, or using 2.0 is best. In regards to the Smoothness that is neither here nor there and comes down to personal preference... But a common setting is 20%.

 

So is there a best factor to use when you're not able to run at X4, or as a few posts/videos pointed out, if one cannot run at X4 maybe its best to leave it off all together?

Try creating custom resolutions. Some games have really bad aliasing though and downsampling doesn't perfectly fix the issue. Borderlands 2 & pre-sequel and hitman absolution come to mind.

I think I found this method of downsampling, you run a custom resolution at I think 2560x1440 or try and push it high into the range of 3200 x 1800 + (largely depends on monitor being able to display it). I had a go at this method and was only able to get the 2560X1440 method to work but never gave it a go in game... I also tried using gedosato a downsampling tool, not sure if it was because I was on windows 10 but even without changing the default settings it made every single one of my games crash at launch.

Yes try the custom resolutions in game and see how it works out for you, but keep in mind that your game might be a lost cause when it comes to fixing aliasing.

Yeah, I am not trying to get it looking perfect, and have gotten use to bad AA to be honest as a lot of titles even massive ones like GTA5 have shimmering even on higher AA settings, not sure if its a result of increasing scene complexity or a failure to properly implement AA as I believe its rather costly to do correctly hence why we see these filter solutions in most games i.e. FXAA. Maybe its as simple as 1080P has had its day and I need to upgrade.
