Im pretty much impressed how much discussion about HoN performance is advancing. So, for some resume of the problem:
- It happens since Catalyst 10.5
- Its just HD4xxx cards issue (or anyone experiencing problem on older/newer GPUs?)
- The OpenGL engine is slower, but not as slow to make game run below playable framerate on these GPUs (i can confirm that as i tried it like 2 months ago on slower nvidia GPU and played the game with all maxed and some antialiasing)
Bridgman? Any comment from AMD side?
PS: Thanks for everyones comment as this bug got enough publicity to get noticed by AMD. Thats exactly what i wanted.
