Hello, I'm new here and have a question about

bojlahg/VanitySearchPublicKey.

if I search there I find only keys with use cpu
-gpu is displayed but does not find any keys
for example:

VanitySearchPK.exe -t 0 -gpu -sk 2000000000000000000000000000000000 -p 633cbe Find no keys but 5000mk/s            (0keys) 1 minute

VanitySearchPK.exe -t 1 -gpu -sk 2000000000000000000000000000000000 -p 633cbe find keys with 5600mk/s very bad (25keys) 1 minute

VanitySearchPK.exe -t 32 -sk 200000000000000000000000000000000 -p 633cbe find keys good but 1000mk/s                (200keys)1 minute

I believe that the program recognizes the GPU
but the gpu performance does nothing

can any help for this

I can't fix this  but I would be happy if someone who can do it would contact me.
