A solution for the blurry bilinear filter of MGS1 to have it razor sharp again, like the native PS1 game

A relatively simple fix for the blurry bilinear filter on MGS 1

First Steps

Me and someone from a different thread found a solution for the blurry bilinear filter in MGS1 for PC. It's not the perfect solution, that would be someone with knowledge changing the resolution of the game in the exe to a specific number, but it's the next best thing.

Anyone can easily test this out for themselves. Just put the game into windowed mode and make the window so small that it would go under 850x478 resolution and voila, suddenly filter gone, near neighbor scale hello.

Slightly under 478p:


Slightly above:

Solution

To now play it fullscreen, the easiest solution I can find is using the program "Magpie[github.com]", with that you can borderless fullscreen the game with a simple button combination in all it's sharp and native glory with the integer scale method of that program. As bonus, with Magpie you can even add upscaling methods like crt scalines, like in an emulator and combinate them how you like.

You really only need the game windowed, scale it down and have Magpie open, choose integer scaling, change the 2x integer scaling option to 4x so it's fullscreen on our 4K TV, and press a button combination. That's it. Fixed.




Change the scaling method here:


Button Combination:

Here is a short video of mine where I show the difference between blurry and not blurry and how simple this works. Nvidia recording unfortunately sucks for me and always freezes the gameplay when I went into fullscreen of the game, so I kept the fullscreen scenes short, but you can still see that it works and I even show of the CRT scanlines.

I hope this could be a solution for some of you.
It's the easiest yet.

Like I said, this solution is not recommended mainly due to input lag, use the new ones/look for alternate solutions.

i have input lag by a whole second. any advice? i use a wired xbox controller

👇plus I wouldn't recommend this solution because it introduces input lag.

Still being worked on but it works fine as is.

Now I got it. I had to set the "general downscaling effect" to none, I had it on nearest before which then can't above the screen technically, and then it scaled past that.
I used the Integer Scale from my guide on 4X, added the effect of CAS_Scaling, set width and height to 1.08 (width too so the aspect ratio stays 100% accurate, and 1.08 because 1.07 still had a few pixels of black bar, but 1.08 doesn't and is now the perfect size without loosing any information, you can activate one of the white wallpapers to measure this size perfectly) and now it's completely fullscreen and thanks to near neighbor scaling it's exactly as sharp as before. So if you really wanted to get rid of the little bars at top of bottom, you can with that, good tip.

That sounds interesting to check out, but I couldn't get it to work. Whenever I try that with type Factor, and on height, it just squeezes in the sides. I don't know know why. If I put the numbers too high I can't fullscreen it at all anymore. Did you change anything else?

[DistantReaper]

Great guide. If you add the effect "CAS_Scaling" and use the height scaling factor - mine is set to 1.07 - you can fill the screen completely without the top and bottom black borders. It looks so damn good.

I hope someone mods the exe, so we can have this regularly. It is crazy that they did nothing to enhance the clarity of the picture.
