| mamarley | RikMills: Have you heard about the compositor improvements in kwin for 5.18? It is pretty awesome. One of the bigger improvements is that GLX_INTEL_swap_event is finally enabled by default, which reduces input lag and eliminates a lot of stuttering and microstuttering! | 15:56 |
| mamarley | (It can be enabled in 5.17 using the KWIN_USE_INTEL_SWAP_EVENT envvar to test.) | 15:56 |
| IrcsomeBot | <RikMills> I have heard bits and pieces. Looking forward to building the beta! | 15:57 |
| IrcsomeBot | <RikMills> Ohh. Nice | 15:57 |
| mamarley | The ironic thing is that KWIN_USE_INTEL_SWAP_EVENT makes my laptop with an Intel HD 5500 iGPU make my desktop with the GeForce GTX 970 look like a laggy, stuttery mess by comparison despite being much more powerful, since it doesn't support that extension. | 15:58 |
| mamarley | I'm actually looking to replace that with something that has integrated graphics since I don't play games anymore, but I can't find anything of the form factor I'm looking for (NUC) that has dual DisplayPort 1.2 (or Thunderbolt) ports… | 16:01 |
| mamarley | It is quite silly because DisplayPort 1.2 can be adapted to HDMI2 for cheap or HDMI1.4 for even cheaper, but the only HDMI2 to DisplayPort 1.2 adapter costs $140 and apparently doesn't even work very well. DisplayPort just gives better flexibility. Just like back in the mid-2000s when GPUs often had a DVI port and a VGA port. Why not have 2 DVI ports? DVI actually has analog pins in it, so it can be passively adapted to VGA, but VGA | 16:06 |
| mamarley | cannot be adapted to DVI at all. | 16:06 |
| mamarley | OK, display interface rant over. Sorry. | 16:06 |
| RikMills | mamarley: nice. a laptop I intend to put Focal on has a Intel HD 620, which looks to be a little but up on your 5500, so that looks promising! | 16:07 |
| RikMills | *little bit | 16:07 |
| mamarley | Actually most/all Mesa drivers support that extension. It only says INTEL because they developed it. | 16:08 |
| RikMills | makes sense | 16:08 |
| mamarley | I had already found that the Intel graphics had less stuttering than NVIDIA on kwin, especially related to creating/destroying tooltips and windows. This just makes it all that much better. | 16:13 |
| RikMills | actually this desktop with Nvidia had an integrated Intel HD on the MB. It might be worth pulling the Nvidia card now | 16:16 |
| RikMills | though maybe too old if this is new thing | 16:17 |
| mamarley | RikMills: Nope, it isn't new. It has been around for quite a while; it just won't be enabled in kwin until 5.18 by default. | 17:57 |
