Hi rbr lovers.

I have an ati 6370 and the games run perfectly but only with original stages and most of the track packs stages like peklo or pribram. However, the game become slow and crispy with country stages and it´s imposible to play. I try to get down the details but the problem still exists.

thanks for your time

Try these values in RBR.ini

ConstantForceMultiplier = -60
Depth = 32
ForceFeedback = true
Fullscreen = false
MinDepthBits = 24
MinStencilBits = 8
ParticleQuality = high -->  low
RenderCarShadow = true --> false
RenderQuality = high -->  low
RunIntro = false
RunStartup = false
Sound = true
UseCubicEnvironmentMaps = true
UseEAX = false
UseSoftwareAudio = false
UseTripleScreenBuffers = false
WaitRetrace = true
XRes = 1440  - 800 mini
YRes = 900  - 600 mini

thanks a lot,

It improves a bit, but not enough for playing confortably

It is a laptop PC and your graphics card is not really intended for the games.

... Therefore it is possible to play in reduced details. Less greedy games such as Fifa 11 or the Sims 3 will be playable in average details.

Normal special "normal" spend more or less well and that you know not to run the BTB who are more intensive in resources.

So the answer is... to avoid the btb stages. However i dont understand why it works bad, i have played recent games such as assasins creed or f1 2010 without problems.

Thanks to all for your time
