Hello, I 've already reported my problem at http://bugs.kerbalspaceprogram.com but i would like to know if some people are in the same case, and also if you know more about that annoying issue. I recently sold my graphic card, an NVIDIA GTX 570, in order to buy a new one. KSP was working fine and smoothly so far, with lot of mods and graphics improvments. I've mounted an old HD 5850 during the time i was waiting for my new graphic card. Since then, i have freezes in game. I mean, the game doesn't crash, but like every 20-30 seconds, it keep freezing during 3-4 seconds. No mods installed for the tests, and graphic settings at the minimum. I was a bit surprised cause i can even even play smoothly with my poor HD4000 (laptop chipset). So, a few days ago i received my new card, ATI R9 290. Sadly the problem still persists. It Looks there are some problems with ATI cards or am i missing something ? Thanks.
