Looks like hardware acceleration has suddenly gone

Lately I noticed that processing files seems to take much longer than it did a while ago. Converting 10 16mp RAW's to 8 bit Tiff (no edits done to the RAW files) takes about 1 minute 30 seconds. In the Windows task manager I can see that all 6 cores of my AMD 1055T are active. I also have a NVidia GTX750 that sped up processing significantly, but these recent timings look like I'm back to CPU only. Is there a way to check whether the GPU is doing anything? Anyone experienced similar problems?

C1 10.2.1, Windows 7, NVidia driver 383.something, 16GB RAM, hardware acceleration "auto".

  Update: tested with hardware acceleration set to never, same timings, around 1:30 for 10 RAW -> TIFF. Adding the graphics card in the past resulted in very clearly reduced processing times, so something must be wrong.
  
  NVidia driver is 388.31

  Solved. The cause might have been the fact that I installed 10.2.1 over 10.2. Uninstall and clean install of 10.2.1 and now the processing speed is where it shoud be: 10 RAW -> TIFF in 15-20 seconds in stead of 1:30.

  Hhhhhmmmmmm....
  
  I was having a nightmare with 10.2 not saving settings.
  
  So, I installed 10.2.1 over 10.2.
  
  Processing, like you, slowed hugely; from about 1 second per file to 2.5 seconds.
  
  I then removed everything from my computer as per this link and did a clean install.
  
  Still the same.
  
  I THINK I did everything right, but I'm not sure.
  
  Any suggestions?
  
  Thanks.
