Radeon Imaging Sharpening for UWQHD/1440p

[Vexr]

It seems there's at least one thorough analysis of Radeon Image Sharpening using a resolution of 0.7-0.8x of 4K then upscaled, with apparently excellent preservation of image quality and a very decent bump to frame rates.

I'm wondering how lowering the resolution and relying on RIS works for 1440p - or more specifically 3440x1440, which shares 1440p's DPI but is getting on toward 4K resolution in sheer number of pixels to push.

I know I'm not alone in asking this having seen this question posed and go unanswered elsewhere.

I had a 1070 Ti with my 100hz 3440x1440. While I know the 5700XT is more powerful than that card in all but an extreme minority of games/settings, the ability to turn 65 fps into 75-80 fps with no real image quality loss would be a game changer in my opinion, and no doubt make the 5700XT > 2070S/2080, yet comments about this possibility are almost non-existent. Where comments do come in, it seems they get a lot of responses regarding FidelityFX on Vegas, which RIS is not.

which RIS is not.

Visually it is. So you can have a go and try it for yourself.

You can use the 5700/XT RIS at any resolution even without upscaling, or if the game supports it.
As long as the game is DX12/Vulkan (I believe DX9/10 supported also, but not DX11) you are fine.

Tested the 5700XT last week on the brand new 4K Freesync TV my mate got. 4K native fps is iffy, but 3200x1800 upscaled + RIS is fantastic.

How do you make the card upscale?

I have a Samsung 4K TV that I'd like to play on, but at native 4K the FPS like you say is a bit iffy, if I could run at 2560x1440p upscaled to 4K that could work a lot better?

The only issue I had running at 2560x1440p it has that slightly blurrier look where it's not running at native resolution, if I can fix/mitigate that a bit could be the way to go.

Above the RIS is a switch "GPU Upscaling". Then set resolution to the games.

Ok cool, so flick GPU upscaling on, run it at 1440p and it will upscale to 4K?

But why? You can use something better resolution as base like 3200x1800.

Ah ok perfect I'll give it a try later on thanks .

Also if the game you play has "resolution scale" setting always use that and keep resolution 4K it works best. But I agree 1800p is a great near-4k resolution. Remember to use gpu scaling (amd control panel -> display).

3200x1800 isn't availabe on my TV I tried to set a custom resolution in AMD driver software but it says not compatible, I notice there are a bunch of settings in that custom res window outside of just horizontal and vertical pixel setting. Don't suppose you have any idea what I could try to get it going .

Sapphire's oc'ing app is getting a Trixx Boost feature for custom resolution+upscalling.

At Timing Standard select CVT, or if that doesn't work then CVT reduced blanking; after changing resolution parameters. Strange you didn't have the 3200x1800 option. I have a Sony and I natively get 3200x1800 and even 3840x1620 in the menu. I only made custom res for 1080p/1440p 120hz. Usually Samsung has even better resolution support from what I hear.

Isn't there an option in games to use that resolution?

Yeah the Trixx app isn't working for me it doesn't open.

Oh I have 3840x1620 but I can't get 3200x1800 working, even with the timing standard changes it says not compatible...

Isn't there an option in games to use that resolution?

There isn't no, I get 1080p, 1440p, 2160p and a few others but not 3200x1800

Does my desktop resolution need to be set to 4k for the upscaling to work?

Have you created a custom resolution on the Wattman -> Display tab, with GPU Upscaling & RIS enables?
You have to type the numbers there.

Yeah thats where I was trying to create the custom resolution but it kept saying 3200x1800 is not compatible with my screen.

Very strange. Give it a go with CRU (custom resolution utility).

I managed to add the resolution and it worked on the desktop seemingly but once I got into a game (Anthem) it was a complete mess lol. I could just about read it and find where to turn the game off again.

I don't really understand I have a - 4K HDR10 43inch curved Samsung TV it must be able to display 1800p because I have a PS4 Pro and I'm fairly certain some PS4 games render at 1800p and upscale to 4k.
