ok this thread is just relating to the epsxe vs vgs one recently posted but i just have questions about it. demigod in your post you stated that nvidia video cards use dd filtering which help the graphics immensely. exactly how "immensely" do you mean? if you have a screen shot of a psx game with dd filtering and one without it would help. thanks.

[Demigod]

Sorry for the long delay in response. Anyways, DD filtering smoothens out the graphics (kinda like bilinear filtering), masking some of the pixels edges and blending the colors. The difference is noticeable but not really "immense", I used the term loosely. I find it gives a smoother, more natural image, although some people don't like the blurring effect. It does wonders for text and backgrounds. Below are some shots to compare.

[edit] some of the shots were too big so they were sampled down but they're still mostly faithful to the original.

Chrono Cross shot with filtering. Notice the edges of the walkway and the structure in the background. There's sort of an anti-aliasing effect to it.

Street Fighter Alpha 3 with filtering. Notice the smooth blending of textures (the eyes) and colors on the statue in the background. Doesn't look as grainy as the one above. But also notice the blurry life bar and score (compared to the sharp one above), which some people don't like.

FF9 shot with filtering. The background is anti-aliased (table in the center) and the text is smoothened out nicely. The advantage of DD filtering for PSX games is that it's a full scene screen smoothing done in hardware so the backgrounds don't display that tiling effect seen on 3D plug-ins.

[edit] Also, because it's done in hardware it doesn't slow down the system like in Pete's screen smoothing filter. In fact it's faster with it on.

DD filtering also smoothens MDECs as well. Below is a high-quality shot of the intro FMV to FF9 without filtering.

Comparison MDEC shot with filtering. Notice the smoothened carpet edges and the text compared to the one above. The ugly dithering around the text has also been minimized.

Those are all the shots I took. I think you get the general idea of the effect of DD filtering. With graphics as ugly as VGS any graphical improvement is a blessing Hmm, maybe someone should move this to the screenshot or off-topic section..

BTW, I think Pete's software plug-in (as well as others) also has DD filtering on them.

mmm... is not the plugin, is just that software renderers use Direct Draw do ... draw ^^<span style="height: 11; Filter: Glow(Color=black)">

seriously what plugin are you using because my radeon 7500 looks a lot better in ff9 than those screen shots. I use pete dx d3d plugin.

Ok, now I am seriously confused. Is this VGS we are seeing shots from? Because I have never heard of DD filtering, and I am positive that I have never seen any graphics look that bad on ePSXe.

I was comparing VGS shots with and without filtering (DirectDraw on Nvidia cards) to show the difference, as Macross_Freek requested. He posted his question it in the epsxe section for some reason. Any mod can feel free to move this thread somewhere else, since it obviously doesn't belong here.

Yes, those are shots from VGS. DirectDraw filtering is a feature of DirectDraw (only enabled on certain cards, 3Dfx cards don't support it, I don't know about ATI) that basically enables bilinear filtering on applications using DD. It only does it for game resolutions lower than the output resolution (PSX games primarily run at 320x240 while VGS outputs it at 640x480 so filtering is automatically enabled)
