It's pretty clear that the DX9 is superior to DX10.  Less aliasing and artifacts and it's faster.  Yes, I said DX9.  

I have FSX standard + SP1 installed on my HP Pavilion dv6000 and it runs VistaHome Prem32bit. I recnetly went to its BIOS and switched its video memory from the default of 64 to 128. The laptop still can't take FSX's graphics goodies when I take all settings slides (I hunted every single one of them via the menu) to their upper limits. In fact, my laptop just froze after a few choppy seconds of displaying. Now I'm forced to have nothing more the first two slides (in General Settings) set to maximum. The scenery slide I leave at minimum since I know it is the real VRAM guzzler. How I can get better performance without replacing my Pavilion?

Another issue I have is, even with my "throttled-down" demand on graphics (General Settings), my B747-400 has "dragonfly wings"; in other words, when it flies -with the wing flexing up- the flexed wing position appears but the unflexed wings also appears..even when viewing the B747-400 in the airplane selector window when choosing /creating a flight. I know something about my laptop's graphics shortcomings isn't handling the wingflexing feature FSX has to offer, please how do I rectify this. Also, when I fly the B747-400 at night, its entire skin excluding doors and wings glows in an "spooky blue" color that reminds me of "St. Elmo's fire". You are welcome to screenshots of this at:

Thanx and I look forward to anyone's opinion/advice/etc.

Oooops, for my "dragonfly-winged B747-400", the link is:

Thanx once again.

In DX 10 screeenshot autogen slider defenitelly lower than in DX9/ Look at hte castle, in DX9 there are trees around it, in DX10 not. Obviously as the result FPS in DX10 higher.
