[XFree86] What Radeons are supported ?
Hi! What radeon versions are ( will be in 4.3.0 ) supported ? I mean complete ( ok 80% ) support with 3D and if possible overlay etc. If I buy a radeon 9500 will it be an EGA impersonator or a 3D monster ?

[Xpert]How are different ATI drivers related ?
Hi! As a future ATI Radeon 8500 owner :-) I wonder about the different available drivers : - xfree86 - dri - gatos - ati.com How are they related ? Do the serve the same purpose or every one does its own part ? ( read : do I install one of them or do I combine them ? ) Is there any overlap in functionality/features ? Code ? Is gatos fully free/open ? How about ATI.com ? Binary only ? Are those FAQ's ? And finally , what is the best ( combination of ) driver(s) out of those ( are there any others ? ) for an end user ?

Here is how it would work : set the display to some resolution ( higher is better ) render your picture ( at a lower , same or higher resolution than the display ) use the overlay to scale the picture to the physical screen cards with good scaling ( filtering etc. ) would make a nice smoothed picture , right ? The only option you mention that could possibly work would be to render the image at a *higher* resolution than the display resolution, then scale the image down using coverage-weighted averaging. This is known as supersampling and is how many AA algorithms work. So is this doable or not ? Your other options would make the image smoother, but only because they would blur the image. More smooth == less alias , or am I missing something ? You can't resize an image to a larger size and get more detail out of nothing. And we don't want more detail, just less alias. The only effect a filter would have would be to smear the image. Examples of use : - text anti-alias : render the text at lower resolution, then scale it up to some higher resolution, and get AA filtering for free - 3D FSAA : render at higher resolution, scale down to get FSAA ( using the same resolution ( 1:1 scaling ) might give something useful too ? ) Opinions ? Unfortunately, that won't work at all. What you want to do is render the text at a *higher* resolution and then scale the result *down* to the display resolution using coverage-weighted averaging. You can't get anything for free! If you tried what you suggest, what you'd end up with would be a blocky character that shows stairstepping, except the stairsteps would be blurry. Not only ugly, but a headache-inducer :-) I think proper filtering would remove the stairs ( the low res ones, the high res ones ( the final image ) depend on the way the RAM-DAC operates ) There are many (and *much* better) techniques for antialiasing fonts in particular that don't resort to this brute-force supersampling method.

Blurrying pictures is not antialiasing them. Antialiasing is subpixel rendering implemented by calculating partial-pixel coverage and mixing the partial-pixel coverages to get an unaliased pixel. Video overlays don't do this. Video overlays perform some filtering , right ? antialias is usualy = supersampling + low-pass filtering. supersampling : use higher resolution low-pass : use overlay hardware Am I missing something ? I admit I don't know how usually overlay filtering/resizing works. ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
