Hi carfesh
jeje, yes, I like user friendly emulators, but not too much he? jaja
About your question, the 2x option, is slower, I cant say how much, but, I can see that solid is much slower than scanlines
I tested 3 games, that I think are less, normal, and high CPU demanding
Lotus 3 = 640x400 - 45% CPU
Lotus 3 = solid 2x - 85%-100%?¿ CPU
Lotus 3 = scanlines - 65-80% CPU
RUFF 'N' TUMBLE = 640x400 - 65% CPU
RUFF 'N' TUMBLE = solid 2x - 90%-100%+ CPU (small-normal slowdown)
RUFF 'N' TUMBLE = scanlines - 85-90% CPU
Jim Power = 640x400 - 80% CPU
Jim Power = solid 2x - 100%++ CPU (big slowdown)
Jim Power = scanlines - 95-100%+ CPU (mm..20% slowdown?¿)
Here a screenshot if RUFF 'N' TUMBLE, the first CPU usage is 1280x1024, 2x, scanlines, and the second is 640x480 with scanlines
Well, for less CPU demmanding games I can use the 2x option + scanlines, that's why I say I love this new option,
good job
