If you happen to have 2 or more profiles in WorldRacing2 I bet you noticed, that it takes a noticable time to switch between profiles. That is because of avatar image is being loaded from your HDD when you switch current profile.
You can speed that up if you rescale all FrontEnd\Daten\drivers\ files for example 25-50% of original size. That won't hurt game looks much, but you'll get a speed-up that will please you
Now profiles will change without a delay.
There's is also the same way to speed up all menus of WR2 - rescale all BG imgaes to 50% or so and you'll notice that now menus are much faster.
