I'm using the open source ones, I guess I should try Catalyst once more (removed it before since it was rather buggy on the desktop, maybe they've gotten better…)


Following the tip at http://wiki.archlinux.org/index.php/ATI ... n.27t_work fixed it for me, didn't have to mess around with Catalyst even :-)

Thanks everyone for chiming in here to help out!

@ patrick_leb: psychose is right to point out the Mesa drivers (this also explains the CPU usage, because everything is being done in software). What graphics hardware do you have on your machine? Can you find a different/closed-source driver? Also, are you willing to take rtcm's suggestion and upgrade to the latest version of Fedora?

@ ttread: Can you find some way to reliably repro the crash? I wonder if upgrading your Ubuntu 10.04 would help you? Alternatively, if you suspect the video driver, is there perhaps a different version that you can try out?

@ kiwibird: Glad you found a fix! Enjoy the game ;-)

@ pyschose: Thanks for posting your log. Since you mentioned ALSA was no good, I was curious to see what audio devices your machine had available. So everything is good for you when running in aoss? Also, just a comment about the vsync: If you have vsync enabled at the driver level, it should ignore the Osmos setting and always be on -- is this what you're seeing?

Cheers all!
Dave

Hi Meal Worms,

yes everything in Osmos works perfect with aoss
and vsync works nice is enable in my driver setting
vsync works nice too for example if i disable in my driver setting and enable vsync in Osmos

I have no problem with Osmos(Demo) :D

I hope someone can buy Osmos for me :oops:

Cheers all!

Sorry I dont understand good my english is really bad

you know what aoss make?

aoss is an OSS to ALSA redirector. You can use it to run OSS-Applications with an ALSA Sound system so you can use multiple programs with audio-output at a time.

I believe the sound problem comes from the old C-Media/Realteak AC 97 soundcard i have the same behavior "sound shuttering and slowdown: sometimes the game produces some cracking noises and the game slower down considerably" under windowsXP with the game "Prince of Persia warrior within" I fix it under windowsxp i turn of the sound acceleration

I have edit my entry with the log but not the log in the entry
I mean money not many sorry :oops:

Wow, Osmos runs very well on Ubuntu 10- even on an unremarkable laptop (ToshSatL305). Nice work!

@ psychose: Interesting! Yeah, that sounds like a problem with drivers for that particular sound card. Thanks for your post!

@ OrbMech: Thanks for the feedback! We went to great lengths to make sure the game performs well on as many machines as possible; glad to hear it's appreciated! :)

I'm having problems with mouse lag while playing the game. The graphics and sound are both fine, but when I move the mouse it takes 1 second or so for the cursor to follow.

Any ideas?

Hi lawsonwa,

Just to be clear, are you referring to the in-game crosshair? And you're playing the Linux version of Osmos, yes?

What kind of framerates are you seeing (hit F1 to display the framerate counter)? If they the framerates are low, does reducing the rendering detail (via the Visual Options menu) improve the situation?

Also, can you please post the contents of your Osmos log?

Thanks!
Dave

Yes, I'm talking about the in-game crosshair. Sorry for the ambiguity. I am running on Ubuntu 10.04.

In high detail mode I get around 15 frames per second. Reducing the detail to low gets me to around 30 frames per second and cuts the mouse lag in about half. I had already reduced the detail when I have the 1 second of lag estimate in my first post.

Here's the contents of my log:

What's your graphics card? You will probably have better performance if you reduce your monitor's resolution for the game.
