usertests Just get FSR4 upscaling to work on RDNA3. That's all anybody wants. Reply
Notton Could AMD offer a beta or prototype Redstone build for RDNA 3? Not right now, according to Zdravkovic — such a release is “currently not in the plan,” but he did thank PC World “for the hint” and expressed interest in thinking through how such a prototype might work. AMD also emphasized that it continues to improve older architectures where it makes sense. Zdravkovic said the company is “definitely not going to withhold anything that really makes a difference,” but only when the net result is a clear improvement to gameplay quality or responsiveness. I guess we'll see if Valve and Xbox can wrangle AMD to officially support Redstone on their hardware. Reply
palladin9479 Yeah this is totally about artificial product segmentation. FSR4 takes advantage of specialized hardware instructions that RDNA4 has, and while it could be made to work with RDNA3 what would be the economic benefit to AMD to do so? If anything it would lower demand for RDNA4 cards as it would be one less reason to convince people to upgrade. Reply
thestryker As much as nvidia does the same stuff they haven't blocked DLSS upscaling even when it will give poor performance (4.5 quality on 20/30 series is slower than native). Upscaling has definitely become a quality of life thing as resolutions and detail have increased along with the prevalence of TAA making native not necessarily looking great. As long as the feature does work it should be enabled for older cards even if it doesn't work as well. Reply

It's not artificial – reading the RDNA 1, 2, 3 and 4 spec sheets do show that several instructions really used by Redstone were added with RDNA4. Proper emulation can be done somewhat with RDNA3, but RDNA2 does need a much degraded emulation to actually work. AMD's code dump showed it, and the results were not universally good – they tried, it didn't really work. Community picked it up and ran with it, AMD aren't discouraging it… Of course I'd be happier with official support, but let's consider the alternatives. Reply
Notton Yeah, RDNA3 does not have, if I remember correctly, FP8 or Sparsity, which is what FSR4 runs on. The RDNA3/INT8 version of FSR4 runs 9~15% slower than FSR3.x, but looks immensely better. 15% performance loss for immensely better image quality is fine, but AMD didn't think so. Reply
