Has anyone experienced issues with using a PowerVR PCX2 in Windows 98SE?
I know that all the drivers that were released, both manufacturer based (Videologic, Matrox) and generic, even up to the latest version (4.1.2) were explicitly designed for Windows 95, but I can't think of any reason why these wouldn't transition over to Windows 98.
Both of my PowerVR PCX2 cards (Matrox m3D and Videologic Apocalypse 3Dx) work perfectly in my Win95 system (see sig)
However, in my Win98 system (for Win98, the 3GB RAM is restricted to 512MB with MaxPhysPage and MaxFileCache), I've had a few issues.
The first issue was the PCX2 not being recognised when trying to install the drivers for it. The Add New Hardware wizard would refuse to recognise any version of the drivers. Eventually, I narrowed this down to a BIOS setting where the initial display device was set to "PCI". Switching this to "AGP" (even though my 2D card is also PCI and the PCX2 is installed in PCI slot 2), seemed to do the trick and now all versions of the driver are recognised by Win98.
I'm not 100% convinced this was the cause. Initially, I thought this had something to do with the PCX2 not being installed in PCI slot 1. However, even when switching to a 2D AGP card and moving the PCX2 to PCI slot 1, it still didn't solve the problem. With the BIOS change, things are working and I don't want to disturb that.
Now, the PCX2 seems to work perfectly for the PowerVR SGL demos and OpenGL based games such as GLQuake (using PowerVR's OPENGL32.DLL) and Quake II (via PowerVR OpenGL).
However, there are some issues with the card being recognised as a Direct3D device.
The card is not recognised by Final Reality or 3D Winbench 98, but it is recognised by 3DMark99 and 3Dfx's WizMark Lite. There also seems to be some issue trying to initiate PowerVR SGL for Unreal v226.
I think the issue with Final Reality and 3DWB98 is simply due to the PCX2 not being recognised as an external Direct3D device. For these, benchmarks I have to choose the "Primary Display Adapter" but ensure I'm using the 3DCC tool and Direct3D is switched to "PowerVR".
However, when running the Final Reality benchmark, the results are comparative to that of my 2D card and not to a historical result I already have based on the PCX2. So, I'm not sure how to test the card with Final Reality.
Has anyone else had some odd results when using a PCX2 with Windows 98?
