You CAN in fact mine Ethereum on a 2GB 750 ti - but I was only seeing 3.something MH/s on mine after tweeking the heck out of them, not worth it IMO.
XMR seems to work ok, though I'm not happy with the pool usually reporting quite a bit less than half the MINER hashrate and the huge number of "nonce don't confirm on the CPU" type messages.
How do I teak mine? I am only mining 1.35 Mh/s. Thank you in advance.
