I just reinstalled a clean ubuntu hardy on my computer (laptop, 64bit os, with an xpress 200 chip) and catalyst 8.5 (was running gutsy with fglrx 8.40 before)... Everything seems fine, everything running normally, but blender is incredibly slow... Not really what's pure 3D (moving big quantity of objects on screen, etc...) but everytime something like menus, texts, dotted lines appear on screen, or if you change your selection of objects, it gets veeery slow.
Has anyone experienced something like this?
Running the same blender version with the mesa opengl lib statically linked runs fine, so it doesn't seem to be a problem with blender... The same blender works still perfectly on gutsy with fglrx 8.40...
Everything fglrx-related seems perfectly correct, aiglx & composite are disabled, direct rendering is enabled, fglrx xorg driver loads perfectly, as well as the module kernel, both are the correct 8.49 version, i tried to switch on/off a couple of xorg.conf options, doesn't seem to change anything... Other 3d apps seem to run fine too...
Anyone has an idea? Something I could try?

I haven't found an apples-to-apples benchmark but at first glance I would expect the 6600gt to be faster than a 3450. The 6600gt has 8 pixel pipes and 3 vertex pipes, with a 128-bit memory bus, while the 3450 is more like a 4-pipe chip in terms of ROPs and shaders and has a 64-bit memory bus AFAIK. Clocks are probably a bit higher on 3450 but not enough to make up for 2x the hardware in the 6600GT.

I guess he thought that any new card must be faster than an old one, but that was a older midrange NV card you compare against an entry level card (at least powerfull for h264 with Win). That's really a but unfair *g*

nah, i didnt really know how good performance would be, though i was quite aware that a 3450 would not be highend
i just wanted to know if fglrx is working as it should.
to be honest i dont much care about that either, what i wanted from the 3450 was something that could be used right away with fglrx, and then test radeonhd progress on

Anyone able to use this driver with a recent .26 kernel?

I can't change refresh rate to 50 Hz. I have 60Hz and I don't have fullscreen on my TV connected dvi-hdmi. When xine finish play a film my X is broken.

yeah it works! with 18.104.22.168 tuxonice and gentoo-sources. and it worked also on 2.6.25. I'm running a 64bit system and i didn't patch the kernel.

Just as a general question...
Just as a general question and also not to insult Ubuntu too much... But, has anyone else noticed the lesser ease of installation of the ATi drivers within Ubuntu 8.04?
I find it rather annoying to have to have all the little extras in the xorg.conf to get it to actually work.
I spent about half hour trying to get it to work last time I format, not really impressed with 8.04.
Maybe it could be that I have about 120 updates I need to install... Some of those may help fix bugs within the system.

touching xorg.conf on ubuntu is, i think, useless, since there are a lot of utilities that help configure xorg properly.

Nothing has been more simple in past!

The Ubuntu situation should be starting to improve; our testing had focused on RH and SuSE distros (that's what workstation users tend to run with) but we're starting to ramp up testing on Ubuntu. The Ubuntu packaging folks are also working hard to make things "just work".
