>I just realized something - isn't the application supposed to change Z test for that ?
I don't know, but all application I tested and which uses alpha test - has z test enabled and all displays errors (tuxracer, enemy territory, fire - from mesa/demos) >Maybe what really happens is that disabling Z test is broken. Z test is not disabled - it is enabled. Problem is - even alpha test fails (and fragment is discarded) z value is still written (and this looks wrong). >On the other hand, as Nicolai points out it would be nice to know what that register does and whether other bits have any function. AFAIK: fglrx initialize 0x4f14 register to 0x00000001, but when alpha test is enabled it sets it to 0x00000000. I have to do more tests to see if fglrx sets this register back to 0x00000001 (for now looks, like it is not set back, but I need to make test program for it).
