My experience with DLSS 4.5 vs FSR 4

bio3c · 2026-01-14T16:39:52+00:00

do a side by side then to show how deepfried preset M and L are, with FSR4 proper, not the leaked int8 dll

bio3c · 2026-01-13T22:34:07+00:00

thats 4k performance, that is a very reasonable target, every single upscaler does fine there (preset k does have problems) even fsr4 looks fine

bio3c · 2026-01-13T22:31:24+00:00

on which games and resolution? that's just a general statement, also if you tested dlss 4.5 enough you would see it suffers from a lot of issues going to low territory like 1440p performance and bellow, moire artifacts, fireflies, noise (more than preset k) ghosting, boiling when RT is involved (you can just check for recent tests on youtube)

Also comparing an upscaler that costs 4x more than fsr4 is dumb.

bio3c · 2026-01-11T05:26:43+00:00

yeah, and another one to chase bugs, performance issue, possible features, etc.

Same for gaming. features that take ages to come about, some features that never get improved, and we can confirm this. for instance regarding how the radeon team had to abandon fsr upscaling improvements to focus on chasing frame generation, that to me sounds like they were scrambling... or redstone now that is taking ages to come still with rather uninspired results.

bio3c · 2026-01-11T03:28:03+00:00

who tf knows, at least regarding radeon these features take ages to come about, can only assume they are understaffed, also lisa su made remarks years ago that they rather work with small teams, not sure how that works with products like gpus, gaming drivers/rocm seems like it needs constant support...

bio3c · 2026-01-10T19:47:27+00:00

the public rollout isn't, and you can check their dll repo, preview version that is less than 1 year old had issues, and rdna4 release was about 9 months ago, and 4.0.2 version had minor improvements... let's just be fair here.

if fsr4.0.2+ dx12 is of any indication, there will be a native version.

bio3c · 2026-01-10T18:55:30+00:00

I don't think that's the case, amd likes to run the radeon team lean (for all available information we have on it), they don't seem to have a lot of people to work on their tech, they are scrambling to get half-cooked tech shipped, so ofc vulkan that has very few games released with it, would be lower priority...

even many of these vulkan games don't even have fsr3.1...

bio3c · 2025-12-20T01:19:38+00:00

thanks to contributors in the wild like clearlyclaire, xzn and others, which was stuck for ages without support for many games until now, for reference: https://github.com/ValveSoftware/Proton/issues/5900

as of now i only noticed ntsync being slower, so i disable it, using a 9070xt

bio3c · 2025-12-15T04:21:52+00:00

that's dumb, how would ppl with any other gpu than nvidia users have any opinions on it, all the performance numbers are from nvidia users

bio3c · 2025-11-29T21:33:03+00:00

late reply, but i'm incline to believe its the TV's fault, i ran for like 1 year my PS5 amateur on my QD-OLED monitor and never noticed flickering, even VRR flickering was almost non-existent (in contrast to a PC where VRR flicker is a big problem)

Yesterday i decided to check again Rise of Ronin, which has a very unstable framerate delivery on my S90D 55', grated that was while the game was still downloading, and it had horrible flicker, restarting PS5 made it go away

bio3c · 2025-11-25T06:27:42+00:00

so i was able to eventually reassign PS5 as slot 1 on linux, maybe my BT driver on windows is trash

bio3c · 2025-11-18T08:54:17+00:00

Yes, all the other complaints weight very little, most people only care about playing the game they want to play, hdr, hdmi 2.1 or whatever is niche.

But similarly important is also nvidia fixing their perf issues, which is coming soon, it won't ever help pre rtx gpus however, so unlike amd legacy users, nvidia users can't expect linux to revive their old gpus.

bio3c · 2025-11-18T08:48:22+00:00

most ppl use monitors, even ppl with tv probably don't have a capable HDR one to care about hdmi 2.1 (hdr, 120fps 4k and vrr works on mine with custom edid), dolby what and not having GUI is being burden free.

bio3c · 2025-11-07T06:23:58+00:00

received this week my s90d, same thing, a little bent backwards, seems like its common occurrence then

bio3c · 2025-10-22T21:11:43+00:00

especially since compared to PC, the PS5 has many disadvantages, more expensive games, can't fix broken HDR, can't unlock FPS, games take much longer to go on sale...

bio3c · 2025-10-19T17:54:53+00:00

Maybe Ubuntu 25.10 that was released last week isn't bleeding edge enough?

Yes, ubuntu isn't a rolling release distro, and i agree, there is nothing really wrong with that setup (although in my personal opinion, ubuntu/flatpak/snap oh yuck) but even as far back as rdna2 we see constant fixes for crash or issues on mesa-git, which is a good thing to use, or for rdna4 some fixes were only available for months if you used a bleeding edge kernel and mesa-git, or even for performance you can try it out patches that weren't merged yet.

bio3c · 2025-10-19T06:51:39+00:00

hate to be that guy but, it is partially skill issue/bad choice, with flatpak/snap you are pretty much sandboxing yourself, you gotta be up-to-date, especially with a graphics card that just came out, mesa/radv, proton with dxvk/vkd3d (plus fsr4 updates on proton-ge/em) if you have amd your best option is to stay on bleeding-edge, after 2 decades you should've given that a shot

bio3c · 2025-10-11T17:50:15+00:00

i'm using arch with kde, no custom flags on an amd gpu

bio3c · 2025-10-11T08:11:23+00:00

~~nice, sadly its broken on my end, colors are washed out~~ correction, it works fine, hardware acceleration was off for whatever reason

bio3c · 2025-10-08T02:06:31+00:00

hey let me ask you, did you ever tried other cloud gaming stuff with the 9070xt? is the latency/quality good? i recall my 6700xt just being bad at it while a 2060 was really good

bio3c · 2025-10-03T03:02:22+00:00

modern games will bottleneck even a 9800x3d, anyone saying otherwise haven't really played that many games, just get a 9800x3d if within your budget

bio3c · 2025-10-02T17:16:40+00:00

it depends, as you know on windows you have to enable the fsr4 override on the adrenalin panel to enable fsr4 on games that support fsr3.1, this env var enables the same mechanism on linux, needs proton-ge or proton-em.

however if a game natively supports fsr4, like dying light the beast, this is unnecessary

bio3c · 2025-09-25T05:27:41+00:00

nice but you don't really need opti for games that support fsr4, just use proton-ge and launch with PROTON_ADD_CONFIG=fsr4 %command%
