Hello,

Every time I use video_switch at a resolution >1280x1024
I receive the message:
“Acknex.exe discovered a problem and had to be closed“
At resolutions >=1024x768 I receive the same message
when I try to close the game (exit;)
(My flatscreen shoud support at least up to 1280x1024!)

When WED is the first thing to appear after the problem
happened I receive this message:
“No hardware accelerated Direct3D devices were found”
and one of the 2d views is empty.

A similar problem appears in some other games too,
when I use a resolution >=1024x768
(800X600 works most of the times)

I use a Geforce 6600GT and got the newest drivers (no Beta).
I also tried old drivers.

System:
AMD Athlon 64 3000+
Windows XP Pro (SP2)
DirectX 9c
GeForce 6600GT
Video-Bios: 5.43.02.80
GeForce ForceWare: 84.21 (newest but no Beta)

What`s the problem?
(Dxdiag sais : No problems found)

What version of Gamestudio do you have? If you own standard, the maximum resolution you can go to is 800x600. Extra limits you to 1024x768, and commercial/professional have no limitations as far as resolution goes. This may be the problem...

He is right no matter what version you have in terms of A5, A6, even A4 or below it all depends on if you have standard, extra, professional/commercial etc.

I'm using A6 commercial.

Can someone help?

When I use “var video_mode=12;” it works.
(my flatscreen only supports max. 1280x1024 and that’s
the resolution I get)

If I try to get the same resolution by:
res_screen=9;
dep_screen=32;
video_switch(res_screen,dep_screen,1);
It crashes when I’m closing the engine.

If I try:
res_screen=10; //or 11,12
dep_screen=32;
video_switch(res_screen,dep_screen,1);
It crashes immediately.

When I tried a different game I received
“error E2000: d3d error: D3DERR_INVALIDCALL”
I don’t know if that’s the same problem,
but I can’t find it in the manual….

Maybe someone can now guess what causes the problem.
