Oh no, I'm stupid... I reported it quadrans ago. Thanks for reminding me.
Ok, here's another issue:
I decided to turn on shadows and bam:
As you can see it looks like the whole terrain is under shadow of something invisible (I know that doesn't have sense...
).
My shadow settings: 1024x1024, 1 sample, 1 kernel size, 8000 shadow distance.
Also look at grass, it looks like rendered properly, without shadow.
Take a look at this low-resolution something ( 0:03 on video ).
Another interesting thing: everytime I spawn truck with 3 button the game crashes... You probably got crash report also. It started to happen after turning on shadows.
Edit: Radeon 3870 + Catalyst 12.6
Edit 2: I changed shadows settings to:
8 samples, 2 kernel size, 10'000 shadows distance. And now it works properly.
