Issue With Multiple GPU Usage
To keep this somewhat sane and reduce the chances of miscommunication, I'm going to refer to the monitors and GPUs as shown below.
Monitor Physical Layout:
GPU Physical Layout:
1 | First GPU | PCIe x16
2 | Second GPU | PCIe x8
3 | Third GPU | PCIe x16
4 | Fourth GPU | PCIe x8
All four are 5870s with 1GB of RAM
Monitor => GPU
1 => 1
2 => 1
3 => 2
4 => 3
5 => 4
Monitor => DirectX Display Name
1 = > \\.\DISPLAY2
2 = > \\.\DISPLAY1
3 = > \\.\DISPLAY4
4 = > \\.\DISPLAY7
5 = > \\.\DISPLAY10
( This is according to the window layout that I'm using )
I've been using four instances of "TechPowerUp GPU-Z 0.7.1" to display the GPU load for all four GPUs. When I launch a basic, two character WoW profile, one shows up on monitor 2 and the other on monitor 4. The monitors that the games show up on matches what is in the Window Layout used for this set. In the WoW config, I have the monitor setting set to "Primary", which is the default. I have tried a number of different monitor settings in WoW with various Window Layouts but not had any luck so far.
When I run both instances of WoW the load on GPU 1 stays in the 30% to 80% range. GPUs 2, 3, and 4 show either zero load or occasional spikes around 3% to 20%.
In terms of ISBoxer's window layout for the profile in use, I have two swap groups with one display and toon in each swap group. Each region has swapping disabled and the home region for the slot is set to the slot with the same number.
Slot 1 = Region 1 = Swap Group 1 = \\.\DISPLAY1
Slot 2 = Region 2 = Swap Group 2 = \\.\DISPLAY7
Questions:
* Why isn't the per-game-instance GPU selection working like it says in the GPU Management wiki page?
* WoW has it's own monitoring numbering system. While the "Primary" option is pretty obvious, is there any easy and reliable way to correlate this with DirectX/ISBoxer/InnerSpace's naming?
* What additional info do you need to answer the above? I've not included every last setting as that'd be a metric ton of stuff to upload and review to make sure there is nothing private in it.
Thanks for your time
