Hi!

 

I have problems with my FSX. I've tweaked it and now I've succeed to get steady FPS @ 30 with the NGX's virtual cockpit at Aerosoft's Mega Airport Arlanda. The problems is, that a weird flickering has appeared, and it's pretty annoying. I know that it's caused by some "command" or wrong value in fsx.cfg, but I have no clue what command it is.

 

Please see this youtube-video, And ignore the soundtrack on it: I was watching PewDiePie's gaming video while recording it.

For first, disable completly autogen (set it to 0), close the FSX, run again and test with the same scenery as ealier. If problem disappeared you know the source. Read this text below for one of the possibilities to eliminate problem:

 

"[bUFFERPOOLS]

Poolsize=0 / Usepools=0 (all the same) - referenced as BP=0

(...)

Water Effects must be High 2.x or higher, otherwise you will get flashes.

(...)

If you get flashing and artifacts with BP=0 tweak, it would be a good idea to check what the GPU is doing - running a GPU at 100% is a source of artifacts, flashes, driver crashes and BSODs. As the CPU sends the data directly to the GPU, and GPU is not able to handle the incoming data, you will get flashing and artifacts, as already mentioned. The only way is to lower the settings, cloud resolutions, or anything basically that is going to give the GPU more headroom, including buying a faster GPU."

Second option may be removing [bUFFERPOOLS] Usepools=0 parameter from fsx.cfg. But it isn't always helping. Raising Water settings to High 2.x works better but makes higher GPU workload as side effect.

I get the same flashing when panning. I didn't have the problem with my 8800GTS, so GPU speed is not my problem. The only scenery I have installed is UTX and GEX, and running UT2. I have done no performance .cfg tweaks.

 

I might try older drivers, haven't done that yet.
