Sapphire Radeon 9550 and OpenGL

Fjtorsol · 04-19-2008, 02:57 AM

Since I installed Vista I can't get OpenGL to work with any app the errors I ge are things like atioglxx.dll unloaded, OpenGL texture compression isn't supported or OpenGL is working in emulated mode.

Hello Fjtorsol

Welcome to TSF

The first thing i would do as this has solved similar issues in the past, is to update your drivers, there has just been a new release of your Radeon 9550 which can be downloaded from the AMD driver Support page. Install this driver, try again and let me know if it has helped or if the message has changed

Regards

Craig

What i've made is to change the motherboard to a new one with a SiS chipset that let's me use openGL in a proper way. The real problem is about via chipset drivers, because in XP openGl worked fine and better if it was with the PCI To PCI controller (used with the ViaAPG slot) that was the default in XP SP1.
So the problem is about Via drivers for AGP slot.
