So, I set up my environment variables in my batch script that look like this:

GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

However, when I actually run the batch file, it's giving me the output below:

'GPU_FORCE_64BIT_PTR' is not recognized as an internal or external command.
'GPU_MAX_HEAP_SIZE' is not recognized as an internal or external command.
'GPU_USE_SYNC_OBJECTS' is not recognized as an internal or external command.
'GPU_MAX_ALLOC_PERCENT' is not recognized as an internal or external command.
'GPU_SINGLE_ALLOC_PERCENT' is not recognized as an internal or external command.

It never used to do this.  Used to always say "SUCCESS".  The miner however still starts to mine with a hashrate of about 115 Mh/s.  Weird.  I did update to the latest AMD Radeon Software Version drivers 17.5.1, and I've had some intermittent crashes in the past since I've updated to these drivers.  I'm wondering if I should roll the drivers back to an older release?  I'm running Windows 10, and have a 5 GPU system (3 RX480s and 2 RX470s).  Just not sure why Claymore wouldn't recognize those GPU_ commands.  Any ideas?
