v4.0 is available:
- Improved speed by about 15-25% (depends on card) on 7xxx, 270(x), 280X cards.
- Improved speed by about 10% on 290(X) cards. For 290X CPD is about 2.6-2.7 now.
- Improved speed by about 15-25% (depends on card) on 7xxx, 270(x), 280X cards.
- Improved speed by about 10% on 290(X) cards. For 290X CPD is about 2.6-2.7 now.
Decreasing GPU clocks and/or undervolting is more efficient, but yes, I will add this option in next version.
