A while ago I disabled DX10 in FSX options, in order to see the textures in an aircraft I downloaded. Problem was, without DX10, FSX would freeze for 10-15 seconds every 10-15 seconds, usually on final approach. I read somewhere that if I put UIAutomatianCoredll in the FSX main folder, it would cure the freezes. Anyway it didn't. I have now reinstalled DX10, no more freezes but cant see any textures in some add-on aircraft, and the shimmering taxiways are I know, a much reported side effect with DX10. Has anybody else had this problem?

Is it freezing because of texture loads? I noticed that performance (untweaked) under DX9 is significantly lower then under DX10 so it may be a performance problem. DX10 was only a preview and for me the graphical errors were pritty terrible but performance was great. I now used Nicks an Jezus's tweaks for DX9 and performance is now the same or better under DX9. Posting some system specs may be helpfull.

Thank's, System specs re my sig. I used *******'s on line tweaking tool. It advised a change from DX10 to DX9, which I haven't done yet, as I'm not sure how.

You already did. When you uncheck DX10 preview in FSX settings it resets to DX9.As for the white airplanes, their textures aren't supported by DX10. I had the same problem.

Thank's, Isn't this for Nvidia GP's? I have two ATI Radeon 5850-1GB's installed.

Opps, teach me not to read your sig. Simforums is a good place to start though. You do need to set up your graphic's card again etc etc
