Issue with Nvidia DLDSR and 21:9 monitors?
Issue with Nvidia DLDSR and 21:9 monitors?
Hi there, I own an Asus VG34VQL1B monitor (3440x1440). I tried to turn on DSR to improve the anti-aliasing effect, but encountered difficulties due to limited support from nVidia. As you may know, they have a long history of problems with this resolution, and despite years of requests, a proper fix never arrived. Some users managed to resolve the issue using third-party tools like CRU or custom DSR, though others couldn't. I fall into the latter category.
What I attempted:
1. CRU: every adjustment with blocks results in a black screen upon loading, and I have to rely on system restore plus reinstalling AMD software—which often breaks unexpectedly. My monitor is a 7800X3D.
2. Custom DSR: it accurately displays the resolution based on my actual display settings, but it’s puzzling why nVidia and applications default to a 16:9 aspect ratio.
The outcome is inconsistent. When I add DLDSR and set the aspect ratio to 4K with refresh rate adjustments, the experience doesn’t work well. The UI—including the nVidia overlay—appears stretched, and even with image scaling and no desktop scale, I still see a refresh rate of 60Hz based on 4K. In some games, I use a scaling factor around 150% in Arma 3, which slightly improves quality but doesn’t eliminate the issues. At 200%, performance drops significantly, causing FPS to fall sharply. I was hoping DL scaling could provide better results without sacrificing speed. Maybe someone has found a viable solution or simply made it function as intended. If this setup works perfectly from the box, does it deliver sharp images with no aliasing artifacts or pixel shimmer? Are all textures visible and clear, or is my understanding of this technology wrong? It seems designed mainly for 1080 monitors, not 3440x1440.
It has basically been a month since your post has been up and no one has the audacity to respond to it but fear not I never back down from trying to help out. It's kind of strange that you wanna run 4K on a basically 3K display there. I mean I shouldn't be complaining, I wanted to see if I could play Crysis 3 in 8K HDR 144Hz Maxed Settings with 3-Way SLI 1080 Tis'. Anyways, I found best solution for me at one point after figuring it wasn't worth it was to use something called Clarity Game Filter in the NV Overlay setting hitting F3 and going to Detail. I find that forcing upscaling for me on a display that shouldn't be is a waste as it make the game or content either blurry or choppy unless you actually CAN find a way to keep it well balanced as much as possible. DLDSR is quite tricky if you've got the proper working hardware for it and can work with whatever resolution you want as long as you can run it or support it with the hardware you have. At the time I wanted to try running Crysis 3 at 8K HDR 144Hz ; I had no idea what I was doing cuz I wanted to see how far I could push 3 1080 Tis' SLI with Bezel Compensation and all that stuff lol but kept getting errors and crashes and such cuz of unsupported memory and . . . you get it . . . Trying to run a 16:9 res on a 21:9 screen will cause multiple problems unless you've got the knowledge of Linus lol by all means do it. I just find it again unsettling. If you wanna play at a higher resolution; test out the resolution via any means and then hard lock it via that means. I turn off any kinds of Anti-Aliasing to cause any kind of overcast of artifacts like you said cuz yes more of it does make it look better but if you enable it to a resolution that is already set makes it run worse. Long story short with this said; it's better if you can handle it lol...................................food for thought...................................
Thank you for your reply and sharing your experience. I reached a similar conclusion using traditional scaling methods. Some games offer such an option, though it isn’t exactly what I was seeking. It alters certain game details to enhance visuals, but not the aspects I wanted to improve. In some titles, higher resolution rendering performs just as expected, although this tends to apply more to older games. I achieved a few satisfactory results by applying 32x antialiasing, which in some cases made my game look excellent without pixel shimmering or loss of fine details, though it wasn’t flawless. I was hoping the DLDSR could deliver a genuine result given its modern technology, matrix scaling, and reconstruction capabilities, but in reality it remains a workaround that depends on a bit of luck and skill to overcome its inherent limitations.
With that said here, there is such thing as perfection but that comes from your own perspective. I find wide screens to be very uncomfortable as their aspect ratios are disproportionate to how I find a game to be realistically sane. I want my game to look like what it be IRL to be on point and not have my enemies look like the Putin Meme lol. Anyways, whatever makes you feel better as a gamer go for it as long as you know that with great tech; comes great optimization responsibility............................................
You're correct about accountability, I returned my 4090 yesterday. I had a week-long break planned to recharge by playing video games... actually, I was able to do that occasionally, jumping from one black screen to another... It's been over a year since those problems were mentioned to GPU makers (and if we count from the third generation of nVidia GPUs, it's already more than three years, I think it's the same issue type). We still have new, cutting-edge GPUs available for professionals. Problems with widescreen displays were reported nearly ten years ago, yet no one seems to address them, even though widescreen is now widely accepted and understood. I identify as a PC enthusiast and can handle many issues, but I don't understand why they continue to persist and worsen instead of fixing or enhancing them.
If you choose to proceed, review it for dependability and ease. I used Palit with double BIOS and multiple power cables—it caused instability and prevented me from performing downvolting. My friend has a simpler version of the same card (Gamerock) and hasn’t had any problems yet. It’s costly, so I think simplicity and stability are better choices.
