Thank you for your replay. I have done repair already and it does not help. After that I have deleted options.lua as you adviced and set options to low- unfortunately without any result too. When I am flying with radar turned off game is very smooth even when I am flying over big cities, but after turning radar on I have 4 to 8 FPS and game is unplayable. If I turn radar off again all is correct - 60 FPS. Have anyone similar problem?

I would like to note that after todays update of DCS 2 I have noticed big FPS drop (from 60 to about 5) when radar of my plane is turned on. It is especially visible when flying Mirage 2000 and F-5. In versions 1.5.4 and 2.0.2 this problem is not present.

How to install 1.5.1.? I have a problem with installing new update 1.5.1 mentioned on forum. I have 1.5.0 open beta installed, but DCS updater does not recognize any updates. What shoul I do?

Problem with C-101 module after updating of DCS 1.5 Hi. I have problem with C-101 module. After todays new update of DCS World beta 1.5 (Update 3), when flying C-101EB i have only about 2 frames per second. All other modules,which I have, works correctly (about 60 fps). Before update (with earlier versions of 1.5 beta) C-101 flew with high frame rate without any problems. Please help to solve this problem.
