Yeah, that looks really bad. The blur is just standard bilinear from what I can tell: turn filtering on, d3d on, hlsl off, and prescale to 1 and you should get equally ugly results.

Out of curiosity what is the recommended prescale setting if you have a powerful PC? 3? 4? And what HLSL settings make the picture the sharpest?

You call it ugly, I call it "Classic Coaxial Video". :P

Prescale is a software integer scaling of the source image before it's sent to the GPU for final processing. So higher factors give you a crisper image at the expense of CPU time. It's purely a personal preference thing; there are no "recommended" settings.

Yes, 3 or 4 is probably the point of diminishing returns. I screenshoted the same image from prescale 1-10 some years back and that was the finding.

Same thing here, at 1280x1024 Prescale 3 looks better than 2 but going above 3 makes no difference.

-prescale is an integer scaling factor applied to the image in both directions. -prescale 3 on a 320x240 game results in a 960x720 image being uploaded to the GPU, so if you're running 1280x1024 there's very little additional scaling for your video card to do and apply filtering on. At -prescale 4 you're uploading a 1280x960 image and there is basically nothing at all your GPU can do with it.

Thanks, I suck at math but that made sense.

I have a question on prescale.
[Re: R. Belmont]
#304841 - 02/24/13 07:18 AM

|

Which ones?
prescale 1
or
hlsl_prescale_x 0
hlsl_prescale_y 0
I'm lost on which ones it is you guys are talking about.

Any of the above I guest. As you would say.
If HLSL is on, hlsl_prescale_x/y overrides the value you've set in prescale.

This was the EXACT same question I had coming back to this thread. Thanks for answering that Sune.
OK I have another very dumb question..... what resolution should I run my games in? My front projector delivers a DLP display with a native res of 1920x1080. I noticed playing Ridge and Rave Racer running them at 800x600 appears to deliver a sharper image than running them at 1280x720. I then tried a much lower res at 640x480....which just happens to be the res those games natively run at...but MAME gives me an "illegal res" error(any way to get around this?).
So basically I'm asking which res do you recommend for overall best picture quality using HLSL on my dlp display?

For the best possible HLSL effects quality you should use the highest resolution you can..that doesn't kill performance. Some settings really put your GPU to work, I don't remember which ones.
