 K900 | Which QEMU can use | 11:03:48 |
 @atemu12:matrix.org | And you need to set up HP manually because QEMU's THP might not actually use HP if memory is too fragmented and defrag can't be done with PCIe passthru | 11:03:58 |

what's THP, and what was before it? THP is "transparent huge pages", which basically means the kernel manages memory in bigger chunks | 11:04:04 |

| K900 | Found a Red Hat blog post | 11:05:02 |
| K900 | 3% performance difference | 11:05:06 |
| @atemu12:matrix.org | In games it's a lot more than that | 11:05:15 |
| @atemu12:matrix.org | Especially CPU-bound ones | 11:05:30 |
| @atemu12:matrix.org | It was a little while ago but something on the order of 10-20% | 11:05:56 |
 crushing-smite | can I automate game installation with lutris on nixos? | 11:13:37 |
| crushing-smite | provide installation instruction for the install wizard, or such? | 11:13:47 |
| @atemu12:matrix.org | Theoretically that's possible but I would highly recommend against it | 11:14:12 |
| @atemu12:matrix.org | Treat game installations as state. | 11:14:22 |
| crushing-smite | would it be possible with some other software? | 11:14:39 |
| crushing-smite | "possible" as "close to a sensible approach" | 11:15:16 |
| @atemu12:matrix.org | Likely but what problem are you trying to solve with that? | 11:15:19 |
| crushing-smite | have my games in dotfiles and nixstore | 11:15:32 |
| @atemu12:matrix.org | And what problem are you trying to solve by doing so? | 11:16:21 |
| crushing-smite | satisfy my curiosity | 11:16:55 |
| crushing-smite | push the boundaries of possible | 11:17:00 |
| crushing-smite | git clone nixos-rebuild switch to install my games | 11:17:16 |
| K900 | You can definitely automate downloading games with something like steamcmd | 11:17:45 |
| K900 | And then build Wine prefixes in Nix | 11:17:52 |
| K900 | But there's a lot of small details | 11:18:00 |
| crushing-smite | for a few select games though | 11:19:17 |
| crushing-smite | mostly old games, but a handful of recent AAA too | 11:19:27 |
| K900 | It's definitely possible | 11:20:08 |
| K900 | But you'll have to set it up yourself | 11:20:37 |
|  @ercao:matrix.org left the room. | 15:14:34 |
