I installed realism overhaul with only US and Soviet Rockets + RSS and i can't play, keep crashing for no reason. With open-gl i can load the menu, enter, and when i click the VAB or similar, in the loading screen i crash .-. . WIth directx-11 i can't even load the menu, but the loading is much faster. What's the problem?I have 64 bit, i5 4590, r9 280 and 8 gb of ram, why i can't even load a single thing? EDIT: I change the texture resolution of the RSS to the mid one, and now i can play easily and at 120 fps o.o (open-gl) . I never see kerbal so fluid and stable, and i crashed only 1 time after playing 2 hours, and in the VAB, not in the fly :3

It was a clean ksp install, no mods were before installed and i have done all in the right manner. In my CKAN there are 3 kerbal space program folders anyway, that's because when i install some big mods i want to have a clean install, like for the Interstellar or the Realism Overhaul. But if the nodes are simply empty because: it' s not a problem, i just wanted to know if these empty nodes are regular or not, for example, which are the last nodes that i must have now?

I have installed it by CKAN, but i recognized that the tech tree have nodes like for the interstellar pack, and many other nodes for other nodes that are obviously empty. So i don't know which nodes must be empty and which nodes must be fill, but is really confusing. So the RP-0 don't show empty nodes?D:

I have a question on Realism Overhaul on the carrier mode, the RP-0: why so many nodes are empty?I should have some other mod installed?And if yes, they are supported by RP-0? I have so much nodes on the tech tree, and like 25 of them are empty... i don't even have the lunar rated heatshield, but i think it's not needed by the way. Which mode or something else can fill the nodes but in the right and balanced manner?
