A way to disable bilinear filtering?

Mar 22, 2014 at 1:42 AM
I'm using PCSXR on Linux and I want to know if there's any way I could remove the annoying bilinear filtering in the default GPU plugin (XVideo Driver 1.1.17)

bump Anyone?

XVideo Driver doesn't use bilinear filtering.

Then how come the emulated screen is all blurred?

Most likely because PSX has low native resolution so without upresing its blurry.

Yes, I figured that one out, but if no bilinear interpolation how come it's still blurry? How would I be able to set the video plugin to use Nearest Neighbour instead? (so I could see square pixels instead of that blurry mess).

So you want to make it look even worse ?

"Worse" is your opinion. You're not helping.

Show gpu plugin settings.

I think it's a video driver issue. %)

Alright, and do you have any ideas of what can I do about it?

Do you have xv output as RGB or YUV? You can see from console output what is selected, f.e.

RGB not found. Using YUV.

PSX image is RGB, and when converted to YUV there could be possibly something funny happening..

Seems to be RGB :)
$ pcsxr
RGB mode found.  id: 3, depth: 24

OK I don't see that effect neither and I am using YUV output.

Can you please upload save state that would lead to state as in those pictures? Then I can do picture comparison.

OK seems that it is not happening on my settings.

It could be that your xv video implementation could be adding it (and could be avoided with some xv flags) or something different happening with RGB output.

If you can, please debug it, and submit a patch.

Unfortunately I don't know C (assuming that's what the project is programmed in) enough to spot the "bugs" in the code nor do I know how to create patches, that's the main reason I came here. If anyone with the expertise could help me out I'd really appreciate it.
