Think I found a mistake in the manual "PMDG-737NGX-introduction" in "SETTING FSX SET UP FOR THE PMDG 737NGX", about " FSX.CFG settings: In the [GRAPHICS] Section: Add the following lines (if they are not already present)• HIMEMFIX = 1• TEXTURE_MAX_LOAD = 4096 I think it should be "HIGHMEMFIX=1", not "HIMEMFIX". correct me if I'm wrong

Yep thats correct. In fact if you use the ******* tool it puts it in for you. The texture load needs to be changed apparently though
