If you deinstall gpxpatch you`ll loose much great features. I recommend that you reinstall gpxpatch cauze on my game gpxsat extensions dont rise avpo as much as on your pc. Only a little bit - not more than 10%.
Try to decrease your fps in gp4 menu (25 fps are not as bad as other sais).
If nothing helps deinstall it but remember you`ll loose good functions.
Try to post this on sdi`s forum. Maybe he can help you out...
