Gallium-V :
I made it work on windows 8.0 with GTX765M and HD4600 combo by creating a new shortcut on my desktop with this path.
C:\Windows\explorer.exe shell:::{78F3955E-3B90-4184-BD14-5397C15F1EFC}
Any name you like.
Then right clicking the shortcut and selecting run with graphics processor and selecting the nvidia option.
Then run as normal and mine uses the nvidia card.
Hope this helps,
Gallium-V
(Yes, I know this is a pretty old post. But I'll throw in because there seem to be a lot of people that still have trouble running WEI for their dedicated GPU)
First, to anyone looking for this solution: Your machine will use the dedicated GPU when it needs to. Why are you so focused on the WEI scores? Their primary value is to communicate to neophytes that there are multiple bottlenecks that affect overall performance (Remember in the old days when consumers really only cared about raw processor speed? Very little care was ever paid to the size of the L2 cache or the timings of the RAM, or the controller used for the Southbridge, or the fact that legacy PCI devices use a shared bus and contend with each other for processing time) The way I use the WEI scores is to grade performance degradation (I'm a software developer). I don't care what the top end of my system is when it's not under load, but I really DO care how it's going to perform when I'm doing my thing. I'm being facetious in posing that as a question, though; I already know why you want to run a WEI with the NVidia card...to show off
I'll show you the scores for my Dell at the bottom. Notice that the difference in the scores don't really mean anything. When I open Unity or ZBrush or Visual Studio, they are always run with the Quadro because I have them registered in the NVidia Control Panel to do so.
To Gallium:
I keep the W7 Godmode link to WEI in my Administration folder, but it never runs against the NVidia card without going into NVidia Control Panel and changing the default graphics device to my Quadro. Then, I {Run with graphics processor | High performance NVidia processor} and it'll run with the Quadro.
I can attest that this method will work correctly, at least in Windows 7.
My WEI scores:
Top line is before switching to run with my NVidia card. Bottom line is after switching:
Processor=7.7|Memory(RAM)=7.9|Graphics=6.4|Gaming Graphics=6.4|Primary hard disk=7.9|Overall=6.4
Processor=7.7|Memory(RAM)=7.9|Graphics=7.9|Gaming Graphics=7.9|Primary hard disk=7.9|Overall=7.7
(Diagnostics run with 4 instances of Visual Studio Ultimate 2013, Unity4.3.2, Chrome (x7), Chrome Metro with 10 live tiles, SQL Server Management Studio 2012, Paint.NET, & ZBrush 2 contending for resources.I feel that the WEI diagnostics are much more valuable performed on a system under normal load.)
Machine specs: i7-3740QM 6M L3 cache, 16GB RAM (1600MHz), 256GB SSD, Intel HD4000 integrated graphics (top), NVidia Quadro K5000M (bottom), $800 for the rig, + $450 for the Quadro (after selling the punier NVidia that came with the machine)
