 elyviere | I usually use https://federationtester.matrix.org/ whenever I need to check if it's down :) | 13:23:48 |
 Albert | hah that's actually how I found it was broken | 13:24:12 |
| elyviere | haha all good then | 13:24:25 |
| Albert | Upgrade from docker 27 -> 28 caused some network changes and my nginx .well_known container was misconfigured | 13:24:36 |
| elyviere | Yea that docker upgrade has been causing me a lot of headaches, not just with matrix | 13:25:03 |
| Albert | I had a few issues.. seem to mostly be fixed now though | 13:25:27 |

| K900 | Holy shit EXTpresenttiming is real | 11:11:00 |
| K900 | * Holy shit EXT_present_timing is real | 11:11:04 |
| K900 | We can have actually good anti-lag now | 11:12:27 |
| K900 | And probably actually good frame interpolation too | 11:12:35 |
| K900 | As much as frame interpolation can be good anyway | 11:12:41 |
 Marie | what is anti-lag actually | 11:18:04 |
| K900 | Basically it's a way for the driver to track the amount of time rendering a frame actually takes | 11:20:00 |
| K900 | And then tell the application to only start rendering when it's almost time | 11:20:13 |
| K900 | So if you have decoupled simulation and render, which you should be doing anyway, you render the most up to date state you have | 11:20:40 |
 magic_rb | Nice nice, time to make my haskell game engine decouple simulation and rendering ig :P ive been eyeing that challenge for a bit, seems like a fun programming task | 11:21:34 |
| K900 | It's a cute idea, the downside is mostly that on non-VRR displays you can sometimes drop a full frame | 11:23:00 |
| K900 | If you miss the deadline | 11:23:06 |
| K900 | And obviously the more frames you're pushing, the less impact there is to anti-lag | 11:25:36 |
| magic_rb | I mean in my case it would be nice to run the simulation at 20tps but run the renderer at 60fps | 12:09:19 |
| magic_rb | Then add interpolation and bam | 12:09:23 |
| magic_rb | Currently everything runs at 60 which for a bg3 like game is unnecessary | 12:09:56 |

 Atemu | I had this odd idea w.r.t. the driver glibc incompat just now that I want to bounce off this room to see whether it's stupid:
Couldn't we simply remove the glibc it was built against from the rpath and assume whoever loads it will bring their own libc?
| 17:16:01 |
| K900 | No | 17:17:33 |
| Atemu | And then build against (but not dynamically link against) some ancient glibc to be compatible with basically anything? | 17:17:43 |
| K900 | Not enough | 17:17:56 |
| K900 | You also need libstdcpp, llvm, etc | 17:18:02 |
