 K900 | https://github.com/NixOS/nixpkgs/pull/425843 Mesa 25.2-rc if anyone wants to test things | 17:25:07 |
| K900 | This should, among other things, expose enough software FP8 to run FSR4 with Proton on RDNA3 | 17:25:44 |
 Charles | oh fun | 17:41:39 |
 debtquity | anybody here able to get marvel rivals running | 20:57:22 |
 woobilicious | Is that strictly RDNA3 if it's just soft FP8? I'm curious how terrible it would be on my RX 5700 XT lol, to bad I don't have any games with FSR4 | 22:05:10 |

| woobilicious | K900: your post mentions Intel-RT on non-x86, does that mean you can run Arc graphics on Arm? | 23:42:59 |

| woobilicious | Reading through the 8bit emulation MR's, there's no mention of it specifically being restricted to RDNA3, there's one bit of code that specifically has "<= gtx11" too, so looks like it might support all models, but maybe I missed something. | 00:04:56 |
 olivia | if you have a link to the MRs, I could double check if you want | 00:41:45 |
| woobilicious | it's more that I can't find any MRs that hint to restricting or even adding FP8 support, it's more that FP8 already works for what ever reason, and they're just adding optimizations.
I just searched FP8 or 8bit and there's only a few results that seem relavant:

| woobilicious | "Georg Lehmann" seems to be responsible for most of the recent work. | 00:48:16 |
| olivia | yeah I'm confused because radv at least is only advertising VKEXTshader_float8 for gfx12+. pretty sure there's no GL fp8 extension | 01:18:36 |
