Dear gentoo amd64 users |
2 |
I've installed doom3 via the emerge command, and I have several problems of |
3 |
performance. I tried several configurations: |
4 |
- when I switch to alsa in doom3, I get very noisy sounds (I get several |
5 |
messages of rejected packets by alsa in the shell) |
6 |
- when I switch to oss, I get huge slowdowns in the game (I think there is a |
7 |
problem with the OSS emulation by alsa) |
8 |
- when playing timedemo demo1 in the doom3 prompt, I get a good number of |
9 |
fps (about 60), but this benchmark is played without sound, so I deduce that |
10 |
I have problem with sounds. |
11 |
|
12 |
All other sound apps work fine (like amarok, kscd). |
13 |
|
14 |
In the kernel configuration, I did not configured any alsa or oss support, |
15 |
just the sound support, and I installed alsa by the emerge command (the |
16 |
version emerged is 1.0.10, the latest stable in portage). |
17 |
I've read somewhere that the command: echo 1024 > |
18 |
/proc/sys/dev/rtc/max-user-freq would produce better synchronisation, but I |
19 |
didn't change anything for me. |
20 |
|
21 |
My question is finally how to get good sounds in doom3 using alsa, not oss |
22 |
emulation. |

Thank you very much |
