I added "-allpools 1" to the mix and did a test using the following configuration and it looks like it worked. I let it run for as long as it took to verify that it connected to the pool and started to submit shares so it may need some more tweaking to get it to work efficiently.
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100

why are you using PTR 0 setting?
first post says to use PTR 1.
I thought PTR 0 is only for ethereum, NOT cryptonote.
