GPL: FSAA working with Catalyst 4.1 drivers !!! w000t

Here is the solution to making enabling FSAA with GPL, as told to me by
snoopy80 on rage3d.com:

"Hey, great news. Just installed the 4.1 cats, and to my disappointment, GPL
was still broken. So I ***** in the forum a bit, and Anemotion posts the
solution to our problem. It's on page 5 of the 4.1 Catalyst thread. In
short, in your Core.ini file, change
DirectMirrorRendering from 1 to 0. It fixed the problem for me. Now we can
enjoy GPL while being able to use new drivers. Hurra!

Adam"

I have one caveat to add to this:  When I tried some back-of-the-pack starts
with Cat4.1, my car and much of the lower half of the screen was gone, and
only reappeared after the race got under way.  I despaired, but after trying
various things, I reduced the Graphics Detail Bias in GPL just slightly from
max detail.  This seems to fix the problem.

Now on my 2.4ghz AthlonXP + 9700pro I'm seeing 36fps back-of-the-pack starts
at 1280x1024 with 6xFSAA 16xAA with all the detail sliders maxed, except as
noted above!   Yay!!

My understanding was that AA doesnt work in GPL because its 16bit, and
ATI wasn't/isn't supporting it.
Mind you I wouldn't want to be ATI and pissing off a whole bunch of
actuall Formula car drivers that use this game for simulation practice.

That happens when there are too many poly's in view, since the
Z-buffer is only 16 bit.

You can solve this by sacrificing a *** at full moon, or, as
alternative, make sure  DisableZBuffer = 1 is in core.ini.

Cheers!

Thanks for the tip about Cat 4.1 and GPL.  I tried the 4.1 driver out and found
that GPL had a lot of "shimmering" in the distance along the kerbs/edge of the
track.  I found the same issue with the 3.9's as well.  Very annoying.  It also
seemed that the frame rate was down by 5-10% as well from the 3.7s that I've
been using.  So, I went back to the 3.7's.

After reverting back to 3.7, I returned here to be reminded of the point about
the core.ini change, which I forgot to try.  Would that change have gotten rid
of the shimmering and improved the frame rate at all?  If so, I'm willing to try
the 4.1's again.

FWIW, my system is an Athlon XP2100, 640 Megs RAM, WinXP Pro, Radeon 9700 Pro
(nothing overclocked).

YMMV.

    This is a non-solution, since it halves framerate.

The former solution it is then - now where do I find one?

Thanks for pointing this out Roger :)

It is soo nice to not have that flickering box on top of the screen.
Those GPLEA cars look just marvelous at 1600x1200 with 2x aa
16 anistropic.

    IRT 3.7, there is one difference that I recall compared to 4.1.  When
pulling out of the practice pitlane at monza, and looking to the left at the
Guardrail, in 3.7 with fsaa+aa turned on I distinctly recall that the
guardrail edges were nice and filtered, with no jaggies.  That's what I
recall anyway.

But with 4.1 and fsaa+aa, the guardrail has very noticeable jaggies, though
once you get out on the track everything looks filtered and smooth.

I'll have to d/l Cat3.7 again and do an A/B comparison, but in any case I'm
pretty happy with Cat4.1 both in GPL and the modern games I'm playing now
(DeusEx2 / Tombraider6 / Tenebrae Quake1).

Anyone have a link to Cat3.7 for WinXP ?  thx

I think that you can still download older driver sets at www.ati.com

You have until February 6th (next full moon) to find one. Good luck.

BTW, I tried Cat3.7, and see no difference compared to Cat4.1, with fsaa
enabled.

In any case computers in the 3ghz+ range with 9800pros should be able to
play this game at 1600x1200 all the time, so fsaa will less and less
important in gpl.

Good news. Just done a Google search and found some islands apparently full
