Systems Specs:-
Intel Xeon 3.4GHz
1GB RAM
GeforceFX 7800 GTX (two DVI outputs)
Configuration 1:-
Only one projector connected to the 7800 GTX.
No extended desktop.
Projector1 running at 1024x768 resolution/60Hz.
In this configuration, I have an application that runs at 60 FPS.
Configuration 2:-
Two projectors connected to two graphics card outputs.
Extended Desktop.
Both Projectors running at 1024x768 resolution/60Hz.
In this configuration my applications FPS falls to 18 FPS.
I tried disabling Vertical Sync, Antialiasing, Anisotropic filtering etc… to see if it inproves framerate. I even tried to reduce the resolution of the projectors to 800x600/60Hz. Nothing seems to improve the framerate from 18FPS. I need atleast 30FPS.
Does anyone has any idea what is causing the a drop in FPS ?
