Hmm did you have the BP tweak before? If not, then the default poolsize is 4000000(if I remeber correct). Im using 0 in pool size, but for the cfg I created for the ATR42 I use 3000000 (or could just remove that mod and let the default 4000000 be used) [bufferPools]PoolSize=0 With this(BP=0) I get extremely poor fps with the A42, but much smoother with the other planes. So with A42 I went from 4000000 down to 3000000, and under that it started to get this poor fps again. So if you did not use this mod(tweak) in the cfg, then perhaps you could add it and try to increase it instead? Not sure about the upper limits thou.(perhaps 8000000?) There is also other tweaks that goes under [bufferPools] but I haven't managed to get other that more stutter with those. Regarding the Video card I doubt that has anything to do with it since the 3D engine is the same(in FSX at least) But perhaps it could be that you have a small memory size in the Video card, and that it starts to swap back and forth when using the a42? Then again I would give it a try to see if increasing the buffer size would help. Be sure to make a backup of your current cfg first. 🙂 Anyone correct me if Im totally wrong about things here.

Hi, I just realised that the A42 don't like small values on BP(Buffer Pool). I discovered that I get like 20 fps in VC and about 12-15 fps outside with BP=0. With BP=3000000 or more I get about 45fps in VC and up to 60fps outside (and steady 30fps locked) I don't know why since every other plane I have works fine with BP=0. Guess there might be some issues with the textures layers/order some how. I have tried to scale them down to a max size 512x512px even, just to test. But same behaviour so it seems not be the texture size(memory) them selfs. Just as a tip for those struggling with this "poor fps" aircraft. I have now 2 fsx.cfg, one for Carenado a42 and one for the rest. 🙂 (32bit Fsx)
