Just getting back onto the topic of other aircraft. I have tested the framerates for the A310 before and after engine start up and there is no discernable difference in frame rates for me. Now that makes sense as going through the folders (there are two for some reason) there are no smoke effect/.spb files utilised for that model. So contrary to what I said before this might or might not be an issue which is isolated to the AN-225. I don't have any of the other iniBuilds models so obviously can't say anything about those.
For the AN-225 it would be great to have the option to have the high-res smoke effects which are part of the model right now, low res smoke effects which are a bit easier on the processor and the option to turn it off altogether.
