JCE,

do I need to do anything special to have my GPU detected/enabled?

I have an AMD Radeon R7 200 I believe.

XMRig detects it but after a few jobs all counters remain 0 or N/A so I wanted to give your GPU version a try.

Edit: this shows XMRig for my card...

[2018-06-23 22:19:09] compiling code and initializing GPUs. This will take a while...
[2018-06-23 22:19:11] #0, GPU #0 AMD Radeon R7 200 Series, intensity: 576 (8/256), cu: 6

not a top class card but the extra 120H/s is better than nothing at all Wink

You need to remove "--auto" in your start line and add "-c confgpu.txt", like this one
jce_cn_gpu_miner64.exe --any --forever --variation %FORK% --low -o %POOL%:%PORT% -u %WALLET% -p %PASSWORD% %SSL% %* -c confgpu.txt

Then edit the file confgpu.txt and change the parameters.
I have done some test with my R7 200 and i go to 140H/s with this parameter (memory at 1050MHz):

"gpu_threads_conf" :
[
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta":4, "index" : 0, "multi_hash":400 },
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta":4, "index" : 0, "multi_hash":400 },
]
