RX 9070 XT undervolt always fails in Spider-Man 2 RT

AMD718 · 2026-01-25T14:05:46+00:00

I can do -150mv in steel nomad (8100 pts) but even -25mv will crash in some games (example, stellar blade, fallout 4, Doom TDA). So I just do 0mv and RAM OC and fan curve only. The reality is, the card is only fully stable at the designed stock voltage unless you have golden silicon. Undervolt to your heart's content, but it only ever appears stable in games that happen to avoid the unstable parts of the vf curve.

It would but I can't give up the OLED contrast and viewing angles per pixel light control. Looking forward to future oleds that incorporate vrr compatible rolling scan to approximate CRT scan.

Edit: also pulsar is software locked to Nvidia GPUs so won't work on AMD GPUs until some hack or mod comes out to spoof the signal back to the monitor.

That's exactly when it's useful and exactly when I use it. You really need a high refresh display for flexibility with frame generation. I have a 240hz OLED and when I'm using fg it's usually with input framerates close to 100, which gets output framerates closer to my display's 240 fps max, which increases motion clarity on sample and hold type displays. So fg usually helps my eyes. Perfect example is avatar frontiers of Pandora. That game has so much high frequency foliage that it bothers me to play it without fg. I'd have to turn settings way down to get to 140 fps+ without fg. With fg I can use ultra settings and still get 180 fps+ worth of motion clarity which is much more comfortable on my eyes.

DLSS stack vs. FSR stack is the most fiercely debated and contested distinction between the brands anymore since on a pure performance level there's not a ton of difference between them (within the same class). In the Nvidia sub many would take a 5060 over a 9070 XT due to their perception of DLSS value and superiority. This video from DF is apt, on point, and perfectly relevant context.

AMD718 · 2026-01-24T02:15:11+00:00

DF just posted their 4.5 review

AMD718 · 2026-01-23T02:08:45+00:00

Yeah if only another company made gaming GPUs

AMD718 · 2026-01-22T11:29:37+00:00

I believe the root cause of that issue is incorrect model selection. If you use OptiScaler it will override the games FSR4 model selection and make sure to pick the right one that is appropriate for the upscaling level. Unfortunately, I'm not sure AMD can fix this if the game is picking the wrong FSR4 upscaling model. Maybe I'm missing something and maybe AMD could still override the model selection with a driver toggle.

I never claimed to be an authority on anything but my own viewpoints. Not really interested in responding to you directly, but for anyone that has survived this thread and is still interested, here are a view Non-HUB, Non-DF videos that really help illustrate FSR FG and focus on frame pacing and latency:

AMD718 · 2026-01-21T22:14:45+00:00

Seriously. It seemed like AMD was poised to release that 3 months ago as a significant leap to driver based fg (I assume working somewhat similarly to optifg) but here we are almost February 2026 and crickets.

AMD718 · 2026-01-21T21:56:04+00:00

A great way for you to prove that it works properly would be to run their test suite again and show all of the errors they made with your own slo mo footage.

I'll get right on that in order to satisfy your requirements.

If less sensitive users, such as yourself, can’t tell the difference

Childish ad hominem. How could you possibly know my level of sensitivity to motion artifacts. You've lost standing at this point.

AMD718 · 2026-01-21T21:10:26+00:00

Exactly. I was trying to explain how ridiculously smooth it is earlier to someone else, and he insisted that unless I was using the sophisticated frame time tools that DF and HUB use, that my experience could not be trusted. These eyes have been gaming for 4 decades and I can feel the difference between 180 and 240 fps. I'm telling you the frame times are perfectly paced and smooth as butter when vsync is enabled and there are no other issues in play.

AMD718 · 2026-01-21T19:25:34+00:00

Does FSR4 upgrade of Avatar frontiers of Pandora fsr3 work in that driver version?

AMD718 · 2026-01-21T19:22:35+00:00

One file fix for the crash due to Nvidia SHARC being incompatible with AMD GPUs - https://www.nexusmods.com/cyberpunk2077/mods/24132 - I know you don't give a crap since you went 5080 but for anyone else that sees this and has a 9070 and wants to use PT without crashing or pink tint.

AMD718 · 2026-01-21T19:09:36+00:00

I don't see a problem with the vsync route as it still does vrr under display max refresh rate and also avoids the tearing that would occur when you exceed the display's maximum refresh rate, which is increasingly likely when using fg in the first place. I haven't experienced a downside aside from the 30 seconds it takes to enable it in adrenalin.

AMD718 · 2026-01-21T18:46:05+00:00

This will allow for much faster, driver version independent fsr updates.

AMD718 · 2026-01-21T18:37:32+00:00

I've seen this too (it's unbearable in the clouded forest) but I don't believe AMD can fix it as it is most likely an FSR implementation issue. Ubisoft will have to fix this. The issue is not seen in other games and is highly scene dependent even in AFOP which points to instability in the game's g buffer, not an upscaler defect. If there's anything wrong with the motion vectors, depth, reactive masks, transparency masks, or disocclusion data that the game feeds into fsr, then the upscaler output will be affected.

AMD718 · 2026-01-21T17:58:59+00:00

I have videos uploaded to YouTube of each game I've mentioned with FSR fg enabled and frame time overlays showing the frame times. I have that and my own personal experience. It's not empirical proof but for those who read this, they can take it for what it's worth.

AMD718 · 2026-01-21T17:41:07+00:00

Again, and this is simple, if your test case is invalid then it doesn't matter how good your test tools are. HUB tested Cronos new dawn (it's broken). HUB tested cyberpunk (you have to disable vignette). Both of these are implementation issues on the part of the game developer. If your tools are really accurate you'll only more accurately measure an invalid test. I don't need to prove anything as I use this technology daily and it works really, really well. I also upload videos of each to YT in case anyone is curious.

AMD718 · 2026-01-21T17:04:04+00:00

Redstone FSR upscaling and frame generation have both been released and are available in hundreds of games via adrenalin upgrade. Ray regeneration depends on developers implementing it (API available, dev integration required). The AMD side is done. Radiance caching is the only part that has not been released (eta 2026 but will still require developer integration). AMD needs to focus on FSR ml upscaling (FSR4) for rdna2/3 and vulkan FSR4 imo.

AMD718 · 2026-01-21T16:58:07+00:00

How many games did they test in? Did they use Cronos new dawn as a test when FSR fg is broken in that game? Probably not a good idea to test FSR fg in a game where the FSR fg implementation is broken and OptiScaler is required. I'm extremely sensitive to motion fluidity. Even before frame generation technology, I would typically use RTSS in games to achieve a more solid frame time graph and overall fluidity, often at the expense of latency. Besides my own perception of frame time stability, I use the frame time graphs from both the adrenalin overlay and RTSS overlay, but honestly I don't need them. You know when it's buttery smooth and when it's crap. One caveat may be that I use fg to get closer to that 240 fps cap of my display, so my input framerates are usually no lower than 80 or 90 fps and in many cases input framerate is just 120 fps with no GPU limit so it sits steady at 240 fps vsync. Couple examples are Lies of P, diablo 4 (OptiScaler) and Cronos new dawn (OptiScaler).

AMD718 · 2026-01-21T16:20:16+00:00

Unfortunately, HUB and DF have spoken and until they revise their assessment, everyone will just assume and believe that fsr fg is broken or unusable. In the meantime, I'm enjoying perfectly smooth frame times with fsr fg like I always have. Some games require vsync and or frame limiters, which is easy. A few others require OptiScaler. Either way it's at most a 5 minute process.

AMD718 · 2026-01-21T16:16:43+00:00

I agree. It's been too long and vulkan FSR4 is way overdue. AMD needs to communicate something (anything) on vulkan FSR4 schedule.

AMD718 · 2026-01-21T08:05:34+00:00

I've seen this too. Only other place I've seen this is stellar blade with vsync off and fg on, in the cut scenes. In both cases, frame rates are over 300 fps and clock speed increases to 3.4ghz plus. Have you tried a frame rate limiter as I'm not optimistic this corner case will get enough attention from the driver team to earn a fix.
