After much hair pulling and resisting urge after urge to dash this infernal computer to pieces, I got JF-15 to work at high res for the first time! Woot!
Details below:
I am running an Intel Dual core and a 9800GTX. I used Zeckensack's .84c glide wrapper. I am posting some screenshots and the actual glide files I used if you want to try. Just move all instances of glide.dll, glide2x.dll, and glide3x.dll out of the windows directory and replace them with the files in the .zip file. In my JF-15 all graphics are maxed and "No page flipping is selected." Hope it works for you.

No graphical anomalies. No smudged HUD text. No UFC text smear. No ghosting cursors. No gridlines. Textures (especially terrain) are crystal clear

There is one catch, enabling A/A or A/F results in ghosting cursor on the HUD, so keep it off. While they would be nice, at this res the sim wont look ugly with them off.
