Question:  Will this work on older gpu's?  I'm trying it out on my crappy laptop w/ an amd A6-3400M w/ AMD Radeon HD 6520G (512MB)(I know, I know, but i like to get use out of the old laptop).  I keep getting an error:

[15:50:16] Error -61: clCreateBuffer (hash_buffer), decrease TC or increase LG
[15:50:16] Failed to init GPU thread 0, disabling device 0
[15:50:16] Restarting the GPU from the menu will not fix this.
