Which is better to play games on the 5660? I've loaded both Nascar Racing 2002 and 2003 and they both have crashed the computer. I ran them with Open GL.

My System:

2.8 gig

512 mb

ATI Radeon 9000 64mb

IMHO, this is my take on them from experience, I haven't read up on the technical sides of them, so no doubt I'll get corrected a good few times.

It really depends on the gcard and the drivers, but usually:

OpenGL +'s
Higher frame rates that D3D
Can handle more surfaces better, and is just in general more steamline than d3d

D3D +'s
Usually more stable
Generally looks better (I believe it supports more software and hardware based technologies)
Basically, because it is MS linked, seems to work better on Windows.

In general, if you are experiencing crashes, first thing I would do is check your drivers, if that doesn't solve it, check your BIOS (Have you got turbo on, or fast read write turnaround for graphics cards etc.?)
And one major thing to have a look out for in any bios is video shadowing, TURN IT OFF! May be great for your MS Office editing, but for games it one of the 7 deadly sins.

Hope this helps a little

I said in any BIOS, I haven't seen an 8887 BIOS< so I don't know what options it provides, but if it aint in there, all the better.

Why would it be better in Office, though? I mean, as opposed to games.

Cheers.

I believe the theroy behind video shadowing is that there is a cache kept of video output, and only changed information from the last image is sent.... which is great if the most animation you are going to have is a drop down menu here and there... but in games that of course isn't the case, so it is better to bypass the video shadowing cache....


That's my take on it anyway from reading motherboard manuals through the years.

Ah, that makes sense. However, there should be a way to fix it, no? I mean, CPUs have the cache on all the time, so...

Cheers.
