The only plausible explanation for withholding FSR 4 INT8 is that AMD wants to push RDNA 2 and RDNA 3 owners toward upgrading to RDNA 4. If that's the strategy, it's a poor one.

That explanation would make sense if we could still assume that AMD is interested in selling GPUs to gamers in the mid-to-far-future. Since they'd rather use pretty much all the capacity they have at TSMC to produce high-margin AI accelerator chips, that explanation doesn't really make sense. I'm glad I took the opportunity to get the fastest AM4 chip, double my RAM to 32 GB and get myself a discounted RX 7900 XT with an aftermarket waterblock.

The way things are going, this may turn out to be my final gaming rig. I have other hobbies I can blow my money on. That equipment also tends to last longer and age better.

I was first confused why someone at techspot would copy a Hardware Unboxed video almost 1:1. But the article was written by Tim himself of HW Unboxed fame.

Anyway, INT8 FSR4 with Optiscaler works really well for me on CachyOS on a 6900XT. I hadnt much luck with the Goverlay integration of optiscaler. But i havent touched it for some updates. But manually dropping in my preconfigured Optiscaler folder with the FSR4 INT8 dll into a games folder works just fine.

FSR4 is pretty awesome even though i used to hate any temporal solution with a passion. But the upscaled output is temporally stable enough with FSR4 in most games. I cant spot the typical smears in normal gameplay anymore. 1080p to 4k upscaling looks pretty good. Its a touch softer than native but i can live with that especially since in most cases the aliasing is better.

Performance overhead is pretty rough on RDNA2 though! Like 3-5ms per frame are used only for the upscaling. Which works well for 60FPS gameplay. But using it to gain eg 120fps is almost impossible.

Would love to see official support. But Radeon gonna radeon.

Just focus on raster performance, fuck all this shitty upscaling crap.

AMD need to get their drivers stable before adding any bs features.
