Flushing shader cache before every FSX start?

Well, if you can't fix the problem, then delaying it so you can finish the flight is the next best thing. And FSX is way beyond repair. The thing is a total disaster of a program, and makes us all look like fools having to build mega super machines and countless add ons to get the thing to run like we think it should. The things we do for our hobby....

Agreed. It would have been nice to see an SP3 with major enhancements to take full advantage of GPU's and 64bit compatibility, would have made it 100% better in my honest opinion.Yes, this hobby is a wallet drainer and with the NGX causing so many to desire an upgrade, that will allow for even more addons to be purchased. You could say PMDG is helping support all kinds of computer/FSX related vendors and manufacturers. Domino effect.

I don't have any facts to back it up, but I think it may if you don't fly in a shader intensive environment after that initial rebuild . After my last cache rebuild, I took the MD11 into some pretty rough skies just to help things along, in case it does matter. :-)Ken Carlin

Appreciate the response Ken and glad you liked the pun. My thinking during this process is that FSX is quite fickle and folks are still learning new ways to improve performance and compatibility. Lets see what happens if I do this or this.. etc.

I don't tweak FSX and I don't have issues beyond those that are inherent in FSX and can't be fixed anyway, so I'm very intrigued why people feel that messing with a few .ini files does anything to fix the problem in the software?It has seemed to me for a long time now that FSX has serious memory management issues, and that the more you fill FSX process memory space, the more likely you are to encounter problems (which tweaking a .ini file will never fix). You may delay a problem, so on your 4 hour flight FSX doesn't crash, but that is all you are doing - delaying the problem.Best regards,Robin.

There are "issues" in FSX that can be fixed and tweaks that do make a substantial difference in performance. I don't necessarily like to tweak FSX but it is very much needed if you want to get the most out of FSX on your hardware configuration. I think many would agree with me on this.
