I previously had Windows 7 installed with Bootcamp on a Macbook Pro mid 2013 with an NVidia GeForce GT 650M. Everything worked well and I was able to use TD (62160) on my second monitor, a Thunderbolt display running at 2560x1440, at 60 FPS.
I just upgraded to Windows 10, primarily to start using a Kinect 2 sensor. TD is struggling and the rendering of the default scene stutters sometime to 1 FPS. I can drag the window to my laptop monitor and then it runs at 60 FPS. If I drag it back to the Thunderbolt, back to 1 FPS. Some things that I’ve tried:
Instead of extending my monitors, I’ve tried mirroring them. TD runs at 60 FPS on my thunderbolt (but the resolution is only 1440 x 900). I also pushed the resolution up to 2560x1440 across both mirrored monitors. TD runs on the the Thunderbolt fine at 60 FPS. This isn’t ideal though as I don’t have two monitors anymore.
I tried extending the monitors again, but dropping the thunderbolts resolution to 1440 x 900. This still dropped TD to 1 FPS on the thunderbolt.
I’ve Got the latest drivers for the graphics card. Windows says I have the latest driver for the display (though it lists it as a “Generic PnP Monitor”)
In the Nvidia control panel I have Power management mode set to “Prefer maximum performance”. I also have Multi-display/mixed-GPU acceleration set to “Multiple display performance mode”. I’ve tried changing both these settings to all available options with no improvement.
