Have you checked the GfxModeExists command to see if blitz3d supports this mode?

i think its a DX7 limitation. On my 30" TFT with 2560x1600 i get the same error (by gpu supports it, even with 3d accel).
when i switch back to 2048*1536 it works fine.

"Have you checked the GfxModeExists command to see if blitz3d supports this mode? "

Yes, the mode is in the list, and when selected fails.

Running in the mak folder fails when the mode is selected from the list.

After testing and some research it appears that DX7 max render size is 2048x2048.

DX9 Removes that restriction to support dual and triple headed monitors.

Since were bound to DX7 we must keep this in mind.

Graphics3D also wonŽt work if you set Window-Mode:

Graphics3D 800,600,0,2 does not work with two Monitors, streched Desktop over both.

Hmmm,... no problems here

I have a dual monitor setup and have no issues. This code works fine.

Graphics3D 2048,1024,0,2

While Not KeyHit(1)


This spans across both monitors in windowed mode. Any resolution larger than 2048 does not work. (due to the DX7 limitation)

Whats your System Specs. Should be a driver problem.

Also DX7 doesnt support 24bpp. Only 32/16. If you call Graphics3D with 0 or 32 into a 24bit desktop, it won't work.

Should be possible. It was not my Computer. DoesnŽt have checked the colordepth from the desktop.
IŽll test it.

Update 13.1.08:
Desktop has 32bit colordepth. 24bit canŽt be selected.

Colordepth should be excluded from checklist, to find the bug ;-)
