Its a addon?

Yeah, I believe it was originally made for the gta games, but was later modified to work (partially) with fsx. There appears to he a more stable alternative available. Richard sennett started a topic today about a different lighting mod that may cause fewer stability issues. I haven't tried either of them.

i have this black screen issue also , when i sometimes switch between full screen and windowed mode, it happened when i move/drag the window mode fsx screen to my second monitor, it happens if a maximise in windowed mode. from what im reading it looks like its a problem with my frame rate limiter i've installed (which is set at 30fps), is there anything else i can do to stop this without uninstalling frame rate limiter? as it improves my FPS over standard in NGX

I assume you are using the Antilag limiter and there is no fix as of yet. However, if you run FSX in windowed mode, you don't need to ALT+ENTER. I've got used to windowed mode now and i get to use what i think is the better of the two limiters.

its an external fps limiter from the "*******" tweaks forum im going to try it tonight without this installed i will also try the anti-lag internal fps limiter to see if the same thing happens
