On GeForce GTX 970 getting worse results. 12.3 ms/iter when running one instance. When running 2 I get 28.6 average. That's about 16% worse throughput.

PRPs on an Nvidia GeForece GTX970

Is there any software that can run PRPs (with proofs) on a GeForece GTX970? CUDALucas only does LLs, and GpuOwL's readme mentions it's meant for AMD GPUs. Anything else I can use?
