Spring RTS Engine

first of all what is a pbuffer.
second, everytime i start the game as soon as it starts loading i get the error: pbuffer creation error: wglCreatePbufferARB()failed!
any clues. Stats are
Windows Vista
p4 ht 3.4 Ghz
1.00Gb ram
nvidia 6800Gt w/newest drivers.

Vista is a beta OS, you should never have it as your primary OS, nro should you expect software support from any vendor or prject for a beta Operating system.

I suggest you check your drivers and reinstall XP and use a dual boot setup, or at least run Vista in a virtual machine, as aside from being a beta OS thats potentially unstable, it could well be the very cause of your spring issues.

For one thing, DX10 beta isn't backwards compatiable, And Vista, to my knowladge, Doesn't support OpenGL. Which ius what Spring uses, Doesn't it?

Vista takes the OpenGL interface and implements ti as a wrapper around the directx interface

I see. so... does that mean it kinda emulates openGL using Direct X?

should be slower than slow then ?

I guess so. The only reason microsoft are even going to put in some kind of OpenGL suppport is taht Nvidia are putting huge support on them to. The idea is, If microsfot doesn't put in OpenGL, Nvidia won';t makes cards that run on DX10, Meaning people who use nvidia will be forced to stayt with XP, Costing Microsaoft millions. Well. At least thats my complicated iidea anyway.

The majority of the industry invovled with graphics is pressuring microsoft not to drop OpenGL as a lot of programs simply cease to exist if it's taken away.

If you are just mapping function call it doesn't really mean emulation and as long as everything matches up it shouldn't slow down anymore then wine slows down on linux... in theory at least... we're lucky MS is supporting what I'm sure they see as an outdated protocol at all at this point.

yeah... they seem to see everything they can't control as an outdated protocol...

Anyway there was someone in IRC a while ago (not you?) who couldn't get it working on Vista with ATI card either. Only OpenGL 1.1 (with only a handful extensions) was supported which is as old as 1995 or so

Go here, download the GLinfo zip mentioned in the link and look what version of OpenGL + which extensions you have.

Too much Slashdot on the brain, matey


But yeah, its prolly standard Machiavellian robber-baron tactics ;P
