Slightly odd that blitting is actually fraction slower than the 32MHz booster viewtopic.php?f=42&t=279 (115% vs 123%) But also off that 32MHz one showing 103% RAM access.. odd..

But I do have a lot more Delays around "bus grant" on this booster.. So I may try reducing them..

Do you think that it might be a clock timing/sync issue between the shifter or other components and the CPU? For instance the 32mhz would still hit the same sync since it is a multiple of 8/16/32 and therefore won't confuse other chips? Just a wild guess :)

Must be NVDI screwing it up, because just tried it and got 126% which is higher than the 123% on the 32MHz one..
