Testing Beetle PSX HW new features


#1

MDEC: Great. I’m gonna use this with Reverse AA shader which improves fmvs sharpness, especially text.

MSAA: Perfect, it allows you to play with a lower resolution compared to your monitor native one by getting completely rid of aliasing, performance loss seems negligible aswell.

Super Sampling (Downsample from internal upscale): this is a mixed one, improves some 2d internally filtered elements, worsens others and downscales polygons. I guess it should be used only with CRT monitors or shaders.


#2

I’ve been testing out Super Sampling and find that it works best on games that use 3D characters on pre-rendered backgrounds. I’ll get some screenshots later, but in FFIX it allows for the characters to fit in the world much better than normal.


#3

Yeah SS is good but only if you emulate on a crt or by using a crt shader. If you emulate by increasing internal resolution to get better graphics is useless, you’ll just lose polygon details cause of downscaling.


#4

Back when I still had my 3dfx Voodoo 5 5500, the glide plugin with SSAA on ePSXe was pretty amazing with 3d/2d background games. :slight_smile:


#5

Here’s FFIX for example with and without SSAA. Vivi fits much more naturally into the space.


#6

For a game like Mega Man Legends 2 that has sharp clean lines you don’t get as much benefit from SSAA


#7

Just another example.


#8

Yeah let me quote myself

#9

Guys, please, explain something to me.

It’s possible to just increase the internal resolution like 8x AND just let the output screen in a way that the shaders can look at it? Don’t downscaling the image (losing quality in the proccess, right?), just tell that the output screen is at 1x.

It’s possible?


#10

No, you can’t increase the size and also not increase the size.

The shaders are (mostly) designed to work with low-res sources. The SSAA option shrinks the high-res images down to low-res for that purpose.


#11

Ok. Thank you hunterk.

One more: it’s possible to create a shader that get a screen upscaled to 8x and then prepare that same screen to a shader like nnedi3 do their magic correctly?


#12

How demanding is the SSAA option for the GPU?

I would like to know the minimum GPU requirement to run SSAA with at least 8x.

Thanks.


#13

Super Sampling? Definitely not demanding at all (i’m playing on a gtx 850m, video card of 5 years ago)


#14

Yes. Super sampling. Can you run at fullspeed with your GPU with at least 8x?


#15

It depends from game to game, but mostly yes.
