Do need it on. The code is less sensitive to CPU cycles than it is the clock, so as long as your computer has enough power to render it should run fine.
I doubt we'll get away from Integrated graphics... They're much more powerful now and sharing solutions tend to suck.
Just tried turning it off.. it still ran.. just a bit choppy- Erik_,Sun Jan 09 2022 12:19am
I was just thinking 4.77MHz because a lot of the games on the IBM PC/XT time weren't controlled by anything besides CPU speed so they ran at light speed once MHz started to increase. I thought turning turbo off tried to re-emulate that speed to make those programs work correctly again. I might just ... more
Thing similar. I had to use it for a game that was running to fast, but I can't remember what it was.
So some systems just slowed the CPU down by disabling caches or skipping cycles. Others really did try to hit 4.77 mHz. I wonder if Delivery Rush can be played on an XT if the graphics were simp... more
