Well, I had the same problem, I managed to fix it by getting up the options (when you open FH sometimes a window comes up, there are two versions, just keep trying to get the right one (try cancel and try again) and there was an option that said RTT Preferred Mode, on mine it starts as FBO, when I tried PBuffer FH crashed but when I tried Copy I was able to see terrain textures ingame. I am not sure if this is the same problem or if it will work for you, it worked for my 5yr laptop (now I have a new comp that works with FBO setting) so it may or may not work for you, plz let me know if this helps
