AMD's FSR 4 aims to close the gap with DLSS, bringing AI-powered upscaling to Radeon GPUs. With 1440p gaming in focus, can FSR 4 match or surpass Nvidia's DLSS? We analyze its image quality and performance.
AMD FSR 4 is Very Impressive: 1440p Upscaling Tested
- Thread starter Scorpus
- Start date
A good start for FSR4. Now they need to show that they can keep improving with constant meaningful updates, not once every half a decade

The hybrid model was already expected to sit between CNN and Transformer, but the ceiling is still higher than CNNs, so there's still plenty of room for improvement.
You can now use OptiScaler to inject FSR4 into DLSS games.
The community was very quick this time.

Still find it laughable that people measure how good upscaling is when the game is freaking paused or running at half speed. That is NOT how you are going to be playing the game, so if you can't notice anything when played at normal speed, then there are no issues.

I find it laughable that people dont understand that you CAN see these issues in motion, Just not on a bitcrushed 480p youtube video, hence why high rez photos are used to demonstrate the issue.

You have to compare it somehow.
People don't seem to get that thr artifacts from upscaling can be felt. Your brain knows something is wrong, but it happens so fast that it isn't sure what. Slowing the images down allows us to see what's wrong and how bad it is.

Older RDNA should be able to run FSR 4 by upcasting the AI model to fp16 or bf16.
The AI will consume double memory but should be ok as many RDNA has 12+ GB vram

Now all we need is an ample supply of AMD cards at MSRP or close.
For now at least in Canada we only got an “ample supply”.

They've only been out for a week, chill out. If we start having supply issues after 4-5 months then we can start complaining. I haven't seen a launch in the last 10 years where the card wasnt sold out everywhere for the first month. If there are supply issues at the end of April or going into May, then I would start to worry. Also, expect another shortage in June as all the kids and college students prepare for summer vacation. The sumer shortage of gaming parts is something I've noticed in just the last 3ish years, maybe it's been going on longer than that. Anyway, if you want a GPU, try to get one in may or you're going to be waiting until the end of August to get one.

You might have missed the MSRP part of my comment. Allow me to be skeptical on the decent availability of close to MSRP units for the foreseeable future.
If I’m wrong, I’ll gladly pay for your beer if we ever meet.
I hope AMD cards sell well this gen to regain some market.
This tech is a great step, we really need everyone in PC graphics to be competitive.
I miss the days when AMD/ATi and nVidia traded blows.

I don't expect wide availability of MSRP AMD parts until May and that's not including tariffs that will bring them to the 720-750 range.
I hate to say this, but if you live in the US, you're better off buying a $700-750 9070XT now rather than waiting for MSRP parts to come out with a tariff tacked on and paying that same money with less of a chance of paying for the "low end" version that costs the same $700-750.
And while I will gladly accept your beer, if these nonsense economic conditions continue I think everyone is going to need a lot of beer. But, hey, atleast Beer is cheaper than soda/pop in the US now. granted, it's the fancy beers, but cheap beers have there place and there are good ones amongst the garbage. Iron City and Yuengling come to mind. a 12 pack of those both cost less than a 12 pack of Pepsi

They all look the same, the only way you’re going to notice a difference is if you zoom in 300% and stand completely, but very uncommon in a video game. Use whichever gets you the most real FPS.

The question is: At what speed (ie -50%) would the eye notice the difference between any scaling technique..?
And the logic is: How much more money is necessary to run native raster, faster..?
And reality is: The more you spend, they less reliance you need on upscaling techniques.
So if you plan to upscale (who plans to?) and sick of using free upscaling in your old GPU's, then buy the absolute cheapest GPU you can find and upscale. Done & done...!
Remember, more expensive GPUs do not have more features.
Lastly, I wholly disagree with Tim's assessment about dlss adoption. As it stand today (whether Tim likes it or not), that AMD's FSR is thee Gaming Industry Standard. Game Developer's first responsibility is to the general populace and share holders... thus Consoles, handhelds and PC.
FSR is thee single solution and highest adoption rate in the industry.

- 9060XT 16GB will probably land around 7700XT performance, be reasonably priced, and be able to use FSR4 tech if the 9070 series is anything to go by.
Just hold tight, will drop within the next month or two.

I’m not sure you’re reading what I’m saying…
I’m in Canada where AMD’s supply of part was woefully low. I tried to get one on launch day but the supply was exhausted in minutes and all I was left with was paying a price which was 15CAD off the price of a “souped up” 5070ti. (1229CAD vs 1244CAD). Sorry, not worth it both of them and even less so the AMD.
This whole industry suffers from Nvidiatitis.
to be honest, I was more concern about the beer when you brought it up because the cheap beer is the only thing in this economy that makes dealing with the economy easier.
I agree completely, but that probably won't continue.
FSR 4 does not work on previous RDNA or any Nvidia GPUs.
However FSR and PSSR are cousins and run on the same hardware.
The only way for AMD to catch up to Nvidia on the software side is by doing alliances like the one with Sony.
For once, I believe Nvidia will get a run for their money. They didn't see that one coming.

Seriously, I can't see any difference. Maybe I need to use a magnifying glass. But when gaming, I don't have time to do that. In a fast moving world, you don't really stop and observe every pixel.
I was never interested in DLSS or FSR anyway. I just want a card that can play 60fps minimum at native resolution. Fine, if the card can only manage 1080p for this.

When we need 300% zoom to see differences, then we know we've reached peak stupidity. In any game the vast majority of these small differences will never be noticed. I see the same analysis comparing lens for cameras where they have to go to 400% and then make claims about how poor one lens is compared to the other, when at 100% the differences are minute and only noticed in the edges of the frame.
TLDR: no longer any need to worry about upscaling quality from AMD.
People complaining AMD didn't release this for older cards have to realise a few things. AMD wants you to buy their new hardware. AMD has to overcome the burden of biased reviewing and has moved heaven and earth with RDNA4 to deliver great improvements in RT and upscaling. To do this most of the driver team were working on RDNA4 to ensure best launch possible. I'll bet my last dollar that 6 months down the track when AMD has shipped a metric crap ton of RDNA4 cards, drivers are nice and stable they will allow the driver team to work on getting FSR4 to work at least on RDNA3 (which has matrix operations). If you had this stuff available on RDNA3 from the outset may people would hold off upgrading at all.
I'm moving from RDNA2 and finally have 4K monitor, so I'm upgrading ASAP, so 9070XT is my next purchase. If I had 7900XT/XTX I'd wait for UDNA5.

The same thing is happening with FSR as it did with Freesync. The open source alternative is becoming comparable to the proprietary one and of course, it will be the one that will remain.
