The current situation is that there is no change to the issue of Hardware acceleration using Dual GPUs and extended displays.

1) Continual crashes with GTX 1050 as renderer giving a nvwgf2umx.dll 0xC00000FD: Stack overflow (HW A NO.JPG)

2) Works acceptably when using the Intel HD630 as a renderer. (HW A OK.JPG)

Comments are as follows:

Reverted the NVIDIA Drivers to v442.92 and the crash occurs in libpersona.dll 0xC0000005: Access violation reading location 0x00000219E6CCEB40. (Dump file is attached)

All crashes using the GTX 1050 as the renderer occur when CPU usage hits 100%, using the Intel HD 630 CPU usage stops before hitting 100%.

Also have attached details of the OpenCL used by each of the GPUs, they are different versions.

Currently OpenCL doesn't seem to work with my setups, the main machine settings that actually work are the following with OpenCL not enabled on either of my GPUs where the issues with NVIDIA drivers means that the GTX1050 cannot be used. This still has flickering when the screen is processed or redrawn:

But, I don't get these issues I see with OpenCL compute acceleration enabled.

In fact it seems that I get better performance from an older PC (17, GT540M) but still cannot enable OpenCL because of the "blocking". Note that there is no flickering of the screen on this PC.

Just for reference, the Renderer doesn't have any impact on the Hardware Acceleration. The Renderer is just the device that we use for presenting the final document to the screen.

Thanks Mark, I understand what you are saying but if I set the performance to this it is OK for rendering and hardware acceleration: 

But it is also interesting that using this setup the Benchmark is:

But with the NVIDIA GTX1050 as the renderer the Benchmark is different, which don't really seem to add up:

But I must add that I have no issues with other products using the OpenGL or OpenCL on the NVIDIA or Intel GPUs, also no problems using Hardware Acceleration but the Intel HD630 is usually way slower than the GTX1050 so there is a little difference here.

4178 vs 4164 and 4715 vs 4702 are not statistically different enough, so they're effectively showing no change (i.e. changing your renderer made no difference).
