Can't you simply dowsample via driver itself ?
One problem with AMD's drivers is, to my knowledge, there isn't any easy way to down sample via drivers. I've looked it up but doing it involves a 3rd party app that doesn't work with some driver versions, etc. Maybe the newest drivers do allow downsampling from CCC? Things change with different displays connected so that may be why I still can't via drivers.
If I recall from what Boris said about the ENB downsampling is that it needs to be a whole multiplier (e.g. 1920x1080 to 3840x2160 or 1280x720 to 2560x1440). The problem is, if you want to downsample from 1440p you have to go down to 720p which will actually not look as good as native 1080p because you're actually losing pixels despite downsampling.
refusedzeroIf you found a good, working method for downsampling with the R9 290 (non-ENB method) would you care to share it? I'd be very grateful! Send me a PM or if there's a good guide online just post a link. Thanks!
I think (Boris, correct me if I am wrong) that AddDisplaySuperSamplingResolutions is locked into factor of 2 scaling of the active display resolution. So, if you have a 2560x1600 screen, and want to render at 3840x2160, you can't. You would first have to set your desktop resolution to 1920x1080, then set Skyrim's resolution to 3840x2160 in SkyrimPrefs.ini...THEN it will work. If you leave your desktop display resolution at 2560x1600, then you would have to use 5120x3200, or if you set your desktop display resolution to 2560x1440, you would then be able to do 5120x2880, but not 5120x3200.
I know this, because I have started using supersampling resolutions myself, and it took me a while to figure out how to use exactly the resolutions I wanted. For a while, I couldn't figure out how to get anything other than 5120x3200 working (which is basically rendering 2x2 pixels for every single screen pixel, or 2x scaling in the horizontal and vertical). I finally created a 2560x1440 resolution via the nVidia control panel (an option that is not available by default), and I was able to get 5120x2880 working. I had to set my desktop screen to 1920x1080 via the nVidia control panel before starting the game in order to get true 4k (3840x2160) working. (I was able to get between 15-25fps at that resolution, too, which isn't all that bad. The real performance hit came whenever I was around particles...any time there were more than a few particles, performance could drop into the single digits.)
I will note, it DOES work, but it can REALLY impact your performance. As Oyama said, it makes everything look so much better...in screenshots. Unlike driver-level downsampling, where the GPU actually filters the full resolution image and actually does downsampling as it pipes it out to over the cable to the screen, currently the AddDisplaySuperSamplingResolutions does not do nice downsampling. It is a very basic form, probably nearest neighbor or maybe some kind of sparse sampling, in order to fit the higher resolution output to your actual chosen resolution. So, if you use this feature of ENB, keep in mind it is really just a screenarchery thing in its current form...you wouldn't want to actually play the game this way. The only way to get the benefit of downsampling for gameplay is to use the driver-level option (which can be much more difficult to apply, and not all screens support it well, and some don't support it at all.)
I don't know if Boris has plans to improve the downsampling algorithm and filtering for this feature. I think it would be cool, but it might not rank all that high in his backlog of features and other things he wants to do with ENB.
