ATI 4830 Low FPS and Garbbled in Jaunty

[muni]

Hi, I put into this problem many many hours, and I got to the point where I am considering buying an Nvidia card.

I have 3 Problems:
1. the right lower corner has a strange pixelation
2. I get a vary low FPS 72-78
3. When I work I dual mode where my monitor and TV have different resolutions I am either I a mode where only one of them is working at a time or the small screen doesn't scale the image and it tries to condense the bigger resolution.

My setup is this:
Jaunty - fully updated
Ati installation propriety drivers, I followed the guide at ati.cchtml
catalyst 9.6
screen 1 1280x1024
tv 1280x720

fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series
OpenGL version string: 2.1.8673

glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately 1/86470 the monitor refresh rate.
379 frames in 5.0 seconds = 75.624 FPS
376 frames in 5.0 seconds = 75.080 FPS
376 frames in 5.0 seconds = 75.080 FPS

re: frame rate, you probably have sync-to-vblank enabled (which is fine) so glxgears is running at the same speed as your monitor refresh. If it's really important that glxgears run fast then turn off OpenGL sync-to-vblank in the control panel.

Thanks for your quick reply, does this effect 2d performance.
where would I disable it? what are the disadvantages or advantages for this setting?
BTW, I have the feeling that fonts don't look right. they are not sharp enough and there seems to be like slight colourful glow although the fonts are white.

No, it will only affect applications using the OpenGL (3D) API. In general you would only disable it if the app you were running had problems with it (eg some apps will end up running at 1/2 or 1/3 of the frame rate under certain conditions.).

It's hard to comment on font appearance without sitting in front of your computer. If the display resolution is being scaled, either by the GPU or the display electronics, then you might get artifacts from that.

The pixellation in the lower right corner might be the "unsupported hardware watermark" if your card has PnP IDs which have not been communicated to the driver devs.

thanks, I appropriated the time took to answer.

I still cant get rid of this annoying pixels at the bottom lower corner of the screen, any one?
