On Windows 98, I recommend restarting the computer after every gaming session, except for really simple windows games like solitaire and minesweeper. Even with that, I still get about one BSOD a day in Windows 98.

The only difference between a RAMDAC and a DAC is the support for 8-bit pallet modes. The "RAM" part is a 256 entry look-up table (LUT) that outputs RGB. The output bit depth of the LUT matches the bit depth of the DACs. So a 24-bit LUT will output 8:8:8 (8 bits of Red, Green, and Blue) to the DACs, …

I recommend the Automated Fix because it includes the ATI rendering patch (tombati.exe) as well as improved cutscene options. The retail fix also uses tombati.exe which provides a windows executable using 3D acceleration (you can render at 1080p for example). The GOG and Steam versions both use …

I remember when this was being developed, and Derek was all over the Usenet forums getting into flame wars with everyone. I think if he spent all that time on his game instead of in the forums maybe he could have actually finished it.

Haven't found a similar simple statement on SMAA yet... There's more than one type of SMAA filter implementation (here's a good reference: http://www.iryoku.com/smaa/downloads/SMAA-Enhanced-Subpixel-Morphological-Antialiasing.pdf). When SMAA is implemented as a post-processing filter that can be …

That is not FXAA or SMAA, that is basically a blur shader across the whole framebuffer from what I can tell. The blur is helping you get around the sharpness issues with the edges, so that is the illusion of antialiasing there, but it's also blurring everything else as well and making you lose …

If you can get Kiosk mode working, you will skip the desktop entirely. You may still get the boot logo, but you could either change that to a black logo or change it to box art for the pingu game (just need to convert to 16 color and follow the instructions Bladeforce provided).

I think what you want to do is to start Windows 3.1 in "kiosk" mode. You do this by changing the shell from Program Manager to pingu.exe. If I remember correctly, you do this by editing SYSTEM.INI and setting "Shell=e:\windows\pingu\pingu.exe".

Does anyone use surround sound anymore? At one time that was going to be a big thing but then it all died away. The widespread use of headphones in online gaming probably has something to do with it.

The power supply generates a good amount of heat, so the PSU fan is typically designed to extract this heat and dump it outside the case. You don't want to blow that hot air into your PC case.

On Carma2, worst-case FPS is at the start of the race when the camera flies down to the starting line with all cars visible. On D3D it would drop down to 15 FPS, while on Glide it would drop to 25 FPS. This is a heavily modified install of Carma2 loaded up with a bunch of high-poly cars and the draw …

Tested Carmageddon 2 with dgVoodoo2 in both Glide and D3D modes. The glide emulation is providing 70% higher frame rate than D3D, with rendering settings identical between the two. Is this typical for dgVoodoo2? I expected the performance to be about the same with either mode.
