i have read in scopes manual that we must disable all graphics accelerations.
i have also read in plantez in discussions that if a vga card is not very powerfull it is better for scope to have more priority from system, something i do not understand.
in my case with agp cards i have used both ati and nvidia, when i lower the graphics acceleration setting then frame rates become slower and pops and glitches appear in every almost movement of a device or window.
if acceleration is full then it is better, faster and without pops and crackles.
why creamware suggests to disable all hardware accelerations of graphics and to set graphics to 16bit as well ???
graphics hardware acceleration
I don't know, but I think it is an OS related issue, because I've done some tests under win 98 and winxp and I've discovered that the graphic is faster under win98 than under winxp.
Maybe under mac the graphic is more faster, I suppose, but I never experimented directly.
Anyone usng mac can confirm?

that's most likely an instruction from 1998 when most graph cards were PCI based and (some) manufacturers were trying to 'improve' their benchmarks by reserving the bus for graphics only (to please the gamers...)On 2006-08-08 07:49, ARCADIOS wrote:

just ignore what doesn't make sense today
cheers, tom
The Scope UI is slower under WinXP most likely because it uses depreciated GDI calls that are technically still supported in WinXP for compatibility's sake but no longer the main supported method for implementing your UI.
Mac OSX's UI is actually slower to the user than WinXP but it's a moot point because Scope only runs under OS9 which is comparable to running it under Win98 on a PC. OS X runs all UI code at a higher level than XP system or user level rather than ring0 which is kernel level. This can cause the Quartz UI (based on top of OpenGL) to get sluggish under high cpu load but for audio work that is a Good Thing as it means that you don't suffer as much from errors do to user interaction. Not so hot for 3d & 2d graphics & animation work though unfortunately. On a PC manipulating a Maya scene with a few million polys is a doddle whereas OSX will tend to lose interactivity as scene complexity grows. Nvidia's quadro drivers have matured somewhat over the years & mitigated this a bit, along with the proliferation of multiple processors on the higher end macs and the improved multithreading in the OS and applications. Background renders no longer affect system interactivity as much as they once did.
Vista will actually move Windows back in this direction to help improve system stability (graphics will run at user level or as a service, can't recall 100%) and give the ability to change drivers without a reboot (supposedly).
Anyway the issues you're referring to in respect to VGA cards and 'accelleration' are definately legacy issues. Turning down 'accelleration' is a way to disable features but there are now better known ways (avoiding problematic PCIe chipsets and using PCI latency tools to manually override aggressive graphics card drivers).
