SOLVED!
(See post nr 3.)


Hey,

I am having quite serious graphical issues.

OS: Win7 Ultimate(BLANK!!! nearly no windows updates, no genuine yet.)
PC: i7 3770, 8GB ram
Graphics: AMD RADEON HD 7800 (2GB)
game version: (latest?) 0.22.30657

List of graphic bugs in menus:
1) No background in main menu [PICTURE 1]
2) No background in character creator.
3) Gameplay mode selection thumbnails (only left column?!) are black sometimes. [PICTURE 2]
(savegames display as ingame screenshot)
4) No game loading background. [PICTURE 3]
5) Occasionally when exiting game (by endtask/ALT+f4) screen filps upside-down.

List of ingame bugs:
1) Most of the time all but HUD is black. (game seems to work; I can walk, interact, have been killed etc.) [PICTURE 7]
2) Other times screen is purple. (found a way removing purple screen by disabling HBAO+, replaces with black/poly) [PICTURE 8]
3) Sometimes one single degree shows a flash of beige (mostly) background. 4) At occasions (1 out of 10 created worlds) i have reached actual polygonal content. (mostly trees) Oddly restricted by ~90 degree angle.(red lines show how far cursor could travel before blacking out.) [PICTURE 4]
5) Most cases objects draw multiple times on screen [PICTURE 5]
6) Menu sometimes displays as seen on picture 6, sometimes doesn't appear at all.
7) Polygonal content is either missing, too bright or black.
Games ability to render anything (menu, poly-content, HUD) seems to be decreasing with time/actions.

List of tests, fixes I've tried.
1) Newest version of gpu driver
2) Changing resolution does nothing but fixes menu buttons.
3) Changing any quality settings doesn't affect anything.
4) Neither does windowed mode.
5) First test with minimal graphics in a creative world added some progress on toolbar[PICTURE 9]
6) Reinstalling game didn't help.

As far as i can tell, game is running smooth on background, sometimes I can see objects annotations and can interact with them. [PICTURE 10].
I myself am suspecting that I might have some crucial files for Unity engine missing, though haven't tried any other Unity games with this new PC setup.
Also environmental lightning seems to play a role as if when object is too dark, it is rendered black.
Looking forward to be able to play.

EDIT:
More recently I haven't been able to render any polygonal content.

PICTURE 1:   PICTURE 2:   PICTURE 3:   PICTURE 4: (out of red lines everything renders black)   PICTURE 5: (most frequent polygonal content. NOTE: DOES change when looking around/moving.)   PICTURE 6:   PICTURE 7: (MOST common thing I see in game.)   PICTURE 8: (HBAO+ enabled)   PICTURE 9: (minimal graphics setting)   PICTURE 10: (objects annotations display occasionally)
