Err, far as I know, transparant crew is something you have to live with. Could try setting "AA Compatibility
20000000: EA Strategy Games" in nHancer, but don't know if that will do anything if you aren't using AA.
Cloud speed is something that is changed by PE4 (as far as I know). If it goes screwy, it could be because of high TC. Don't exceed x2048 TC.
Haven't been playing much lately, kinda awaiting new RFB release. Let's hope someone who is more up to speed on these issues has any suggestions. (wink wink)
