I have HD 5750, and I've installed Catalyst 10.7 for it... but the graphics are still "unsmooth".
Second issue, is that my mouse pointer / cursor is moving unsmooth too.
One more issue is about my Monitor: I have LG M2362D, and auto-adjusting says it's 1280x960, when it's 1280x720 (driver from CD has no problems).
One more thing I can mention, is that Catalyst 10.6 / 10.7 "strikes out" some MB's Bus driver when removed.
Okay... last one: latest Catalyst doesn't includes HDMI Audio driver for my HD 5750.
Can you comment on this?
