New Version 11 - opencl.dll was not found

[AntonG]

A little upset. Paid full-price (no return customer "upgrade" discount is disppointing) and found errors that interrupted the completion of the 3D mark section.

This version was probably not ready to exit Beta and be prime time released.

There are two major interfaces in use for video card compute (compute = running general purpose code on GPUs).
One is Directcompute and the other is OpenCL.

nVidia supports both interfaces on Windows x86 for all recent video cards.

But we use OpenCL in V11 because Windows for ARM based CPUs doesn't really support DirectX very well at all. Directcompute is basically missing (so badly emulated that it is broken). But OpenCL is available.

So it should just work, on all 2000, 3000 and 4000 series card from nVidia (and we have tested this on a selection of cards).

As this is brand new card (likely an upgrade we are guessing) we suspect you have installed the latest video card drivers for this new card. That error message in your screen shot is a general one from Windows when a required DLL is missing, it isn't from our code.

As background a DLL is a file containing a library executable code that is typically used by many different applications. In this case opencl.dll isn't supplied by us. It is supplied as part of the video card driver install.

So we'll also make some changes in the next patch release to check for missing Opencl device drivers and produce a better error message. As the error message should point people towards updating their video card drivers.
