RBR uses a fixed track, in MBWR you have a whole complex landscape, which is
quite detailed, even with planes flying around, in which you can drive
around anywhere you like. The road has subtle specular highlights. Don't
forget the other very detailed cars on the track, which look much better
than the cars in RBR. I said that MBWR looks a lot better than RBR and it
does.

Actually I'm running it at 1400x1040x32, no AA ofcourse, I never use that.

Hmm, I see the latest Omega drivers have a new GUI, AF is at application
preference, probably off then, though I see no texture shimmering like I see
in RBR (it's pretty terrible there). Texture and mipmapping quality is at
max. Truform and VSYNC are off.

Anyway, I don't know what kind of framerate a dog gets for breakfast but
it's running quite smoothly here (moreso than I remembered even), that's on
a 1.3GHz Pentium-M (2.0 Ghz P4 equiv) 512MB laptop (currently with virtual
memory turned off). It's certainly not choppy in any way and the framerate
is quite stable as well. It's very playable with my MOMO Force wheel.
There's either something wrong with Steve's setup (maybe memory speed or
driver-wise?) or I have a magical laptop :^) Or Steve is used to very high
framerates. If it wasn't playable I would have reduced the display
resolution and amount of colors obviously.

BTW, that was with all my startup applications, viruskiller, firewall, WLAN
etc. and even Outlook still running in the background. LOL here comes the
kicker, I had my laptop still set to 'minimal energy use', meaning it was
running at 600MHz :^D Trying again at 1.3Ghz... probably slightly smoother,
not a whole lot of difference, main difference is that the laptop's fan
comes on now :^)

Not to start comparing apples and oranges, but I would consider CMR5 and LFS
both quite visually pleasant games with a lot of environmental detail.  In
LFS at the rather poly-intensive city courses, with 8 other AI cars running
in a race, I'm seeing 70 - 110 fps at 1024x768x16, and this is on a ThinkPad
notebook with a 1.7 Pentium-M and the so-called dog-slow Radeon 9000 chip.
Likewise CMR has pefectly acceptable framerates in the 50+ range.  I'm not
suggesting the chip is a world-beater, but I also think that it has enough
muscle to provide a good driving experience in many current sims.  None of
us are arguing that the early Radeons are not out-of-date in terms of
performance, but merely stating that, given the fact that we are satisfied
with the 40 or so fps we get in RBR, can't we just get rid of the *!$&%
flashing scenery?!

Well, in any case, my understanding is that it's a problem with ATI's
drivers and there's a group of people over at RSC trying to lobby ATI to fix
their drivers so that they can run RBR on some of the lesser Radeons.
