Mid 2014 graphic switch glitch

Please explain what you mean by this...
Also, have you reset SMC and NVRAM? Are you switching GPUs with an app?
When an App that requires the dGPU there's about a 5 second black screen when it switches from iGPU to dGPU. For now I disabled "Automatic graphic switching" in the power settings.
This started happening when I started using the nVidia Web driver and installed CUDA driver. The Graphics performance is way better but the black screen may be an issue since it needs to seemlessly switch between graphic cards.
Ok thank you for the answer to the questions.. still have no idea what you mean by "web" driver.. I have had very little success finding a functional graphics driver besides what updated with my OS X installation. I too have the CUDA driver.. but I do not experience this issue. Restart your mac, hold shift when you start logging in(disables login items) and see if the issue continues.. Did you reset SMC?

nVidia has been on their game in terms of releasing good drivers for their cards. This is the latest. The performance is much nicer than the stock OS X drivers which Apple never updates. I am able to get more performance in CUDA based applications.
Recently nVidia opened their drivers up to more than just the cMP, and now MacBook Pros with nVidia GPUs have access to these drivers.
I will try resetting the SMC and report back. Thanks!
