thank you for looking.
Have the game (GTA4) installed and working now on Windows 8.1 x64.
Z87 Sabertooth Mo-bo.
Asus 1080p monitor.
Problem is, it will not let me adjust the GRAPHICS settings. Nowhere, nohow.
Can adjust keyboard setting etc... But not graphics...
I can see people have it working with a GTX 780 in Hi-Def (on youtube), but HOW ?
Game is set as RUN AS "XP" and one shortcut to "RUN AS" Vista, but neither let me adjust graphics.
I get this message on the Graphics adjustment page;-
"\warning; Your graphics settings are near, or exceed, the suggested resource limits for your system. It is recommended that you reduce your graphics settings in order to run the game optimally."
"Resource usage 202/3072Mb"
So I try and reduce the settings but they are already set at the lowest.
Every time I try and do the "BENCHMARK" it crashes halfway through.
I have the latest Mo-bo drivers. The latest Windows Updates. The latest NVidia Drivers. Everything is updated and run every other game perfectly at 1080p, except this one.
