Kano: michaellarabel: GLX Version 3.3.0 NVIDIA 256.52
Kano: michaellarabel: http://www.nvnews.net/vbulletin/showthread.php?p=2309077
michaellarabel: Thanks Kano
Kano: just installed it
Kano: did you test squeeze yet
dandel: Kano, it appears opencl 1.1 support is broken on 32 bit systems for ati :/
Kano: never tested
Kano: video support and unigine heaven is all i test
dandel: all i did was run the 32-bit opencl samples on the stream sdk
Kano: win is still slower when you compare opengl
Kano: especially when tesselation is used
Kano: dx11 was faster
dandel: then keep an eye and post responses on the unofficial bug report: 1873
Kano: i did not notice that nv drivers are faster with linux, maybe within a 5% range
dandel: i expect near identical.
dandel: i would expect this bug to be fixed quickly: http://ati.cchtml.com/show_bug.cgi?id=1888
Kano: well you dont get 100% exact driver version to compare
Kano: so it must be slightly different
dandel: i said near identical.
dandel: that means if on windows i am seeing 90fps on a program, i'd expect to see 80+ fps on linux
Kano: btw. i test with a 5670, pretty slow
dandel: Kano, i think that bug is a regression
Kano: dandel: maybe you did not get it, opengl is FASTER with linux
Kano: from 12 to 16 fps
dandel: i contacted the dev of the application and he says it works properly on 10.7 with a radeon hd 4770
dandel: but he can't get catalyst 10.8 to run on his install :/
Kano: thats why i have got a script to do that ;)
dandel: i'll send him the link to the script that helps.
Kano: if you want correct driver version in amdcccle
Kano: login into vt1
dandel: does that work with ubuntu 9.04?
Kano: sudo /etc/init.d/Xdm stop
Kano: rmmod fglrx
Kano: sudo sh install-fglrx-debian.sh
Kano: sudo sh install-fglrx-debian.sh -z
Kano: -z does not kill x, but is much safer
Kano: you reboot then
Kano: when you switch from oss with kms you have to use -z in any case
Kano: i can do that within screen for nvidia
Kano: but fglrx always crashed when i used that code
Kano: the problem with the fglrx version is that when you install the driver and you reboot only but x was running then /etc/ati is written on x shutdown
Kano: that will write the old version there
Kano: replace X with g or k or whatevr
Kano: and best use -z...
Kano: dandel: if you want to compare it with 10-7 or 10-6
Kano: just add -v 10-6 or -v 10-7 as extra option
Kano: if you are in the lucky case that you get beta drivers put em into /usr/src
Kano: and use a simpilar option,just with the version
Kano: my script will add missing signatures on the fly ;)
Kano: 10-7 is a bad tess test btw
dandel: hmm... his bug was 10.8 couldn't let him start the x server 0o'
Kano: tess will only work with 10-6
Kano: dandel: rm -f /etc/X11/xorg.conf*
Kano: maybe befor
Kano: in his case
Kano: i have got pciid patching now too with a normal xorg.conf
Kano: when there is none aticonfig will be used to create the base file
Kano: err not pciid, busid of course
Kano: i needed that because some systems did not startx without busid setting
Kano: dandel: i think there is a fix for your issue
Kano: dandel: add addiontally to my script -u
Kano: that will update packageing from phorogit on the fly
Kano: the new default is x760
Kano: in the commit before
Kano: will need a switch for maverick then in case of xorg 1.9
Kano: and a new override for debian style packages...
Kano: like debian experimental
Kano: dandel: i might add the fix directly, when you test it...
dandel: Kano, not the problem i am describing.
Kano: dandel: the opencl problem should be fixed that way i guess
Kano: in theory
Kano: well then i will not add a patch
Kano: -u is the way to go
dandel: that fixes the first issue i had
Kano: with the sdk
dandel: i informed the package maintainers about a week or so ago.
Kano: so maybe i add the small patch, it will be a bit longer for what i need it as it only patches source in git,but i need other postitions
dandel: the 32-bit opencl bug is because the ati drivers only bundled the 64-bit opencl 1.1 implementation and not both.
Kano: well from the code it is lucid+ only
Kano: that error
Kano: i currently do not even have got a lucid install
dandel: here's my bug: http://pastebin.ubuntu.com/485237/
Kano: the codepiece just adds those files
Kano: to update-alternatives
dandel: that is me running clinfo on both 32-bit and 64-bit binary.
Kano: will do that tomorrow, then i will tell you when the script is updated that you dont need -u
