My system is an i5 4670k @ 4 G, 770 gtx, latest drivers, windows 8.1
Running EECH 1.15 on fullscreen mode I get a low framerate of 20-25 FPS. The low framrete is present even in the main menu (mouse movement and text animations). Switching to windowed mode in eech.ini resolves the problem (50-100 FPS). I installed according to the guide at EECH central: http://eechcentral.simhq.com/index.php?title=Installation_guide
I tried the following, which had no effect: lowest menu gfx settings @ 640*480, changing the FPS limiter in eech.in to 30-100, drivers: vsync on/off/adpative, power managment - "prefer maximum performance". I also tried 1.15.2 RC3 exe.
Any other suggestions? The window has borders which are distracting in flight.
I'm using the DS exe's as I don't have OpenAL - could this be an issue?
