- If you run your WB at 72Hz you might have noticed that the
- mousepointer isn't as smooth as it is under AGA.
- Quick fix:
- run >NIL: vt >NIL: S7 DE=0 work:graphics/pics/1x1pixelbrush.iff
- Put the above line in your user-startup and the mousepointer
- will be smooth again...
-
- Well, what does that strange looking commandline do anyway?
-
- (I hope you are famaliar with run)
-
- vt -> ViewTek, can be found on aminet. (gfx/show/ViewTEK21.lha)
- S7 -> super72 (a 72Hz mode)
- DE=0 -> Shows the picure for 0 seconds...
-
- The 1x1pixelbrush.iff is any picture but preferably a small one.
-
- Would be even better to write a small program that opens a
- very small 72Hz ECS/AGA screen.
-
- I think all this is because CyberGraphX doesn't "patch" the
- WaitTOF() routine.
-
- Running your vertical blanking at 72Hz gives a little more
- overhead but I could hardly notice it with CPUmeter.
- (0.5-1.0% extra load, maybe)
-
- BTW, works on my A3000/25/CV64 and OS3.1.
-
- PS. If you run your WB at 60Hz under CyberGraphX you could try
- changing S7 to NT but the change is not as great.
- DS.
