I've seen this mentioned a few times on other forums, but haven't found a
solution.  With the ATI Radeon card, the scenery flashes on and off.  The
ground, car, moving spectators etc are rock steady, but all static scenery
(trees, crowds, bushes etc.) flash on and off.  Very annoying.  If I hold
down the Print Screen key, everything stays in the image, but of course the
framerate drops to the cellar as it is writing screenshots to a memory
buffer.  Anyone else have this problem, and has it been solved?  Driver
issue?  Patch?

Same problem here. And as I'm using a laptop, I can't simply upgrade my
videocard.

I haven't come across a solution for it yet, it's not even clear yet if it's
a problem with the game or a driver problem. I think they should also add an
option to turn off pixelmapping (I think that was the term for it) to
improve framerates on lower-specced machines.

I guess it's just a matter of waiting until I can finally play this game,
it's a bit frustrating.

I have this problem as well with my 8500. I bought a used 9800Pro, cause I
got reeeeally fed up :-) It should arrive today.

There's a workaround that works for some (it did for me): Hold the [PRINT
SCREEN] button when you're in the game, and the flickering should (almost)
disappear. As long as you hold [PS] the fix will stick, but touch any other
key on the keyboard after that, and you have to press and hold [PS] again.
You'll see.

That said, ATI has just released new beta CAT drivers (v8.07 beta), a hotfix
for Star Wars KOTOR:
http://www.ati.com/support/infobase/4649.html

I believe they are based on CAT 4.11, due out in november (current CAT =
4.9). Anyway, Omega has released a new driver set based on these betas, and
this is what it says in the readme:

I don't know if this fix addresses the 'flickering' issue, but you might
want to try it...

I'd try another driver. I have a 9800 Pro and no flashing, using the 4.2
driver.

To Stephen F:
Apparently I overlooked that you were already mentioned the Print Screen fix
(and it didn't work for you). Sorry :-)

This bug only affects a few cards: 8500, 9000, 9100, 9200(?). Anyway, the
9800 Pro is not one of them, AFAIK. I agree it's probably a driver issue
though.

As I mentioned, Print Screen kills my framerate.

Thanks for the tip!

I tried them out but unfortunately they didn't solve the problem. I didn't
really expect them to solve it, because that would be a really fast driver
fix.

Have you tried the new Omega drivers as well?

Those cards are so old and/or slow that the game wouldn't be playable
anyway.   I wouldn't even think about playing this game on anything less
than a 9500 Pro.

In that case they should do something about that, because Mercedes World
Racing runs perfectly fine on my Radeon 9000 and it looks much better than
RBR.
Adding an option to turn off the pixel shaders would probably fix the
framerate well enough, those are only used for dirt on the car and window
and fog anyway.

The scenary in RBR is at least 3x more detailed than in MBWR.

Just out of curiosity, I installed MBWR on my second PC (P4 2.66GHz with a
9200) and it ran like a dog's breakfast to put it mildly.

Dont worry Steve i think he failed to tell you that his Radeon 9000 runs
MBWR at 320 x 240 x 8 bit and with AA and AF at minus figures... ;P
