Agreed with Casey, in my experience, this is caused by using RDP (Windows Remote Desktop) to connect to the computer. TeamViewer (without the TeamViewer monitor driver being installed) or VNC should work instead. Also recommend checking this out: communities.bentley.com/.../25254.changing-graphics-card-settings-to-use-the-dedicated-gpu-on-a-windows-computer In addition, in the Windows Power settings, set to 'high performance' and in CC Master, recommend that you experiment with the 'Target RAM' value... in testing, using 16 GB (out of 128 GB on the machine) was the most optimal and tasks completed significantly faster than any higher value. If you are using CC Centre (distributed computing), then use VMs (on a hypervisor such as UnRAID [KVM] or VMware vSphere) each directly assigned a GPU and 16 GB RAM, should yield significant speed improvements. In addition, there were improvements in performance that came between Windows 10 updates and NVIDIA drivers found during testing. Edit: Also if you're using Windows 7, then locking the computer might cause the GPU acceleration to be disabled - either use Windows 10 (which doesn't appear to suffer from this issue) or ensure that Windows doesn't lock during processing. You might want to check the NVIDIA Control Panel to ensure that there isn't any 'automatic graphics switching'... the GPU responsibility going over to an integrated GPU to save power (in the NVIDIA Control Panel, you can set the GPU to 'high performance' mode which might help with this). In addition, 1. Check BIOS settings for the motherboard and how it handles GPU power settings 2. Use a fresh install of Windows [ideally Windows 10], with just NVIDIA drivers, Windows Updates and ContextCapture being installed. In my experience, Chinese-made software conflicts a lot with other applications (for instance, Qihoo 360 Internet Security 安全卫士 has caused me a lot of issues previously), so attempt to restrict unnecessary applications if possible. One more thing, noticed that you are running an old version of CC (04.04.0.338), this is two software revisions old and there have been many bugs fixed since then (04.04.05.33), so if you can, I'd recommend updating.
