Gminer Ravencoin Hashrate Issues

I was originally using Teamredminer to mine Kawpow + Zil with RX 5700 XT. The hashrate is perfect on there but it's very unstable. The computer gets very laggy and crashes too much. I switched over to Gminer and it's much more stable but I can't seem to get the hashrate higher than 15 MH/s.

I need help either fixing TRM so that it doesn't crash the computer or get Gminer to increase my hash to about 25 MH/s.
