Alternative to bilinear filtering with Direct3D at 15khz 368x240

This effect is caused by using d3d instead of D-Draw. Mainly on vertical games displayed on a horiz monitor. D-draw is causing slightly choppy motion objects which bother me. The D3D smooths things out, but text and certain m-objects don't look right.

I enabled the bilinear filtering and it fixed that problem, but gave images a "soft focus" look which kinda drives me crazy 'cause it makes me think my monitor focus is off. Is there any tricks to keep the D3D and make things look right without using the bilinear filtering?

What kind of monitor are you using?

Go snag a cheap ATI video card and use Calamity's modifed drivers to run all your games at Native Res x 2 on a regular VGA monitor for pixel perfect displays:

I'm using a regular WG 7000 series monitor with an ATI x1300 pro agp. I'll check out the driver hack....

If that is just for VGA res, then it doesn't apply here when I'm running std res.

Didn't know you were running on std res. No, running at VGA resolutions is not the default configuration.

With the configuration you've described though, it should be fairly straight out-of-the-box from the drivers. It's AMAZING what a difference running the games at the native refresh rates makes. It's such a small difference in timing, but it really makes things feel more like the original hardware.

Screwed with this again for a minute today. Rotated a vert game sideways (so it actually was displayed vertically) and it looked right. So I guess I'll just deal with it until I have the stuff around to build another cab and dedicate one to vert games.

Do yourself a favor and ditch D3D and install the custom ATI driver + groovymame (see the groovymame forum here).  You will be amazed at the results.
