Leaked FSR4 INT8 Test: RDNA 3, RDNA 2, Steam Deck, Asus ROG Ally, Nvidia + Xbox Series X Simulation
Added 2025-10-13 18:45:23 +0000 UTCUpdate: This video has been updated - the strobe warning is more pronounced, an error in voiceover has been corrected and individual frame-time charts have been added to the Alan Wake 2 test.
Original Post: Hi everyone, as mentioned earlier - some All-Supporter early access action, as what was initially going to be a pretty simple test for FSR4 INT8 on the RX 6700 turned into something hugely more time-consuming and extensive.
The blurb: a new version of FSR4 was recently leaked by AMD (!), opening the door to high quality upscaling for any GPU that supports INT8 machine learning instructions. That means a range of products ranging from every RDNA 2 or RDNA 3 based GPU, including Steam Deck and ROG Ally handhelds. Rich takes a look at image quality and performance across a range of devices - including Nvidia (double !) and even ballpark simulations of how FSR4 could run on Xbox Series X.

Hi! My English isn’t very good, so I’m not sure if I understood everything correctly :) Is the first FSR4 prediction for the PS5 Pro considered good or bad? Thanks a lot!

2025-10-15 02:26:58 +0000 UTCFYI, this video (both the unlisted and public versions) play at max 1080p resolution on the native (WebOS) YouTube app on my LG G4 even though the video has a "4K" tag there. Also, DF Direct #235 plays at max 1440p there, but both public videos play at 4K max on YouTube app on PS5 (Pro) and on macOS (Chrome) as expected. All other public 4K videos play at 4K quality just fine on the LG YouTube app, so it's specific to those two videos. Are those using a different 4K codec or something?
