 olivia | so I had assumed the normal pipeline looks like "render all your non-UI stuff at low res" -> "feed to the upscaler" -> composite with all the UI | 07:20:45 |
 K900 | That's how it usually goes yes | 07:20:52 |
| olivia | and the driver can't tell the difference | 07:20:54 |
| K900 | But with driver injected FSR2 it just runs on the entire frame | 07:21:03 |
| K900 | Which is not great | 07:21:09 |
| olivia | yeah that's fucked | 07:21:14 |
| K900 | But it kinda works and they get to advertise a feature for MORE FRAMES | 07:21:18 |
| olivia | I just learned that fact a couple days ago when reading about fsr4 is my mind is boggled | 07:21:33 |
| K900 | I still remember magic D3D9 fourccs | 07:21:47 |
| K900 | It's just always been like that | 07:22:00 |
| olivia | yuck | 07:22:18 |
| olivia | I've mostly never actually had reason to learn d3d stuff | 07:22:28 |
| olivia | so managed to avoiding knowing this lol | 07:22:39 |
| K900 | https://aras-p.info/texts/D3D9GPUHacks.html | 07:23:07 |
| olivia | do people actually use it? | 07:23:07 |
| olivia | or does it come out looking so wonky that you don't bother | 07:23:15 |
| K900 | ¯\_(ツ)_/¯ | 07:23:18 |
| olivia | fair | 07:23:22 |
| K900 | I haven't really tried it much | 07:23:23 |
| olivia | honestly the whole concept of NN upscaling has seemed pretty unappealing to me | 07:24:46 |
| olivia | what if TAA artifact on steroids sounds bad | 07:25:13 |
| olivia | * "what if TAA artifacts on steroids" sounds bad | 07:25:23 |
| olivia | this is so awful | 07:30:37 |
| olivia | thanks | 07:30:39 |
| olivia | so is there a better way to expose vendor extension features now, or are they still doing nonsense fourccs in d3d12? | 07:31:47 |
| K900 | I think the way you do this now is you just dlopen a vendor specific library like libnvapi or libamdwhatever | 07:34:46 |
| K900 | And that does who the fuck knows what really | 07:35:00 |
| olivia | ah | 07:36:43 |
|  mwlabs joined the room. | 09:18:27 |
 woobilicious | Driver based tunables have been a thing on windows for ages, you can force 16xAF and 8xMSAA since like 2004, MLAA, transparent texture AA have been toggles too, something that should be part of Linux tbh. Nvidia's drivers have thousands of per-game hacks too, it's one of the reasons why Nvidia were so popular, they were squeezing performance out of every game title by breaking DX11's guarantees selectively, also game devs are built different, Unreal ships with perfectly fine TXAA, and some games just change the default settings and make everything look like garbage. | 10:16:46 |
