System Config:-
1 HPxw9400 workstation.
2 GPUs (QuadroFX 4400G + QuadroFX 4500G)
1 G-Sync card (Primary -> 4500G & Secondary -> 4400G)
4 Monitors (2 in HorizontalSpan on 4500G & 2 in HS on 4400G)
WindowsXP + DualCore Intel CPU + 3GBRAM
From the NVIDIA Control Panel:-
The 4500G is configured as Master with internal framelock signal source. The 4400G is configured as Slave and synchronizes with the Master’s framelock signal.
Application code:-
2 OpenGL windows each one covering 1 horizontal span. So 2 (DC, RC)'s.
Enabled the 2 devices for G-Sync and checked its configuration.
Win1 -> HS1 -> 4500G -> Master -> Internal source -> Enabled
Win2 -> HS2 -> 4400G -> Slave -> External source -> Enabled
I reset the counter on the Master device. So far the setup looks fine.
When I render to the win1 & win2 and call swapbuffers on both sequentially it takes a while (about 15 sec) to display the frame and gets worse for subsequent frames. Application runs fine without G-Sync, no stall everything is smooth and real-time.
Are 4400G & 4500G compatible ? If so, is it possible to use both GPUs on the same machine as I’ve done ? Is there anything else that I’m missing in using the G-Sync ?
