I finally found the reason why the game is laggy and has bad graphics when using win8 and an ATI card. The problem is driver related.
I think the game starts in softwareaccellerated mode if there are no opengl drivers. So to fix this:
- Go to device manager
- Go to the Display adapters
- If there is a bracket with(WDDM 1.x) behind the graphics card, this fix will work
- http://support.amd.com/en-us/download go to that site
- Search for the video-drivers for your card
- download the installer
- run the installer until you see a welcome screen
- cancel now, dont continue with the setup
- go to the Folder where the drivers got extracted
- in my case it was C:\AMD\
- continue with going to C:\AMD\Support\xx-x-legacy_vista_win7_64_dd_ccc\Packages\Drivers\Display\W76A_INF
- in the W76A_INF folder should be some files like ch... and c7...
- Dont run anything in here.
- copy the path of that W76A_INF folder by clicking in the top-bar of the explorer (CTRL+C)
- go back to the device manager and rightclick you graphicscard
- select update drivers(1st option)
- select "search on harddrive for driversoftware(2nd option)
- select "choose of a list of drivers...(below the field were you can type in a path)
- select harddrive (above cancel)
- paste the path(CTRL+V)
- there should be at least 1 new driver in the list
- select new one(the one that is named like your card, not wddm and not basic adapter)
- click on continue(the screen should go black a few times)
- Exit the menus
- check the device manager and see if the wddm behind you card is gone
- start hammerwatch, enjoy the awesome game
This fixes the game, at least it did for me, it also fixed other opengl using games like minecraft
