What is Mipmapping in San Andreas? 

I'd highly recommend watching this on a PC or big screen in HD if you can. The comparisons are hard to see if you're viewing on a mobile device, even in HD. The train track texture is actually from an older version of ROSA. ROSA Project Evolved actually contains a much nicer texture, thanks to Junior for pointing it out! ----- Socials: Instagram - instagram.com/_tjgm_/ TikTok - www.tiktok.com/@tjgm_?

Mipmapping actually gives you more FPS but it will use more memory (which is neglible in the case of GTA SA)

Impressive to see this is a Playstation 2 game , and they used custom autogenerated mipmaps specifically for the console , they really tailored the Rendereware engine to they favor, an open world game of that scale running directly from the disc to the measly 32mb PS2 RAM

This train track texture isn't from RoSA, we would never use a texture like that in RoSA, we use the original source from Texturama.

Even as someone who knows what mipmapping does, this was a very interesting watch! Mipmapping also makes the games some fraction easier to run as the game doesn't have to load the highest resolution image for far away objects.

I am writing some manual "mip mapping" code. But I am a self-taught graphics programmer and I had never heard the term "Texture Crush" before. Definitely adding that to my vocabulary.

Part of it comes down to supersampling/averaging. In a conventional image, every pixel is essentially a mix of everything in that image that would occupy that space if you imagine the pixels as a tiny grid of boxes. Every photoreceptor in your eye is gonna show you an average of all the different bits of light hitting it, the same with a camera sensor. But with realtime 3D, it's like its shooting out an infinitely thin ray and whatever it hits gets displayed. So a pixel that you'd think should be half blue sky and half green leaf is gonna be one or the other. Creating hard edges, and a lot of flicker. That's why supersampling (i.e. MSAA) was a popular form of anti-aliasing. Just make each final pixel an average of a larger group of pixels. Somewhat effective, but very slow. If you just created a mipmap by downscaling the texture with the most basic nearest-neighbour texture sampling you'd still have tons of aliasing, because those low resolution textures would be aliased too. But instead it's downscaled with something like bilinear or bicubic sampling that is turning 4 pixels into 1 by averaging their values, creating that smoothness. So effectively mipmapping is eliminating the need to do supersampling across the whole final image, by pre-emptively applying averaging to the textures. If you really wanted to, you could do the same by keeping textures the same resolution and just blurring them because it's the act of averaging out pixels that is creating that smoothness.

I don't know why but I like the crispy look of textures when mip mapping is disabled

A fun thing to do is edit each mip map texture to a different hue, then you get a colourful visual of which textures are being used at all times.

I know what Mip Mapping is but this video is more informative for people who do not know what Mip Mapping is and want to know about it. This video contains all the information about Mip Mapping and the audio is very clear and the technique of persuasion is very nice. appreciate it 👍🏻

1:25 Disabling mipmaps steals Ryder's car!

Me watching in 240p: 👍

You're really good at explaining stuff.

You explained me a MIP mapping better than my professor in my computer graphics lecture, pure king.

Playing San Andreas again because of your guide and the mods people have put together, those people are the best part of the Internet.

Hey man! Please make a video on MIXSETS. It is one of the most important mods made for GTA Trilogy Classic especially for GTA SA. BTW love your videos.

Very informative, i hope you'll make same in-depth videos about other technologies

great video once again, i love your presentation style :)

Great video, I've always wondered what that option did!

I have previously noticed this effect when you play a high resolution video on a small screen such as a phone. Native resolution always looks smoother. Another nice video 👍

Thanks for the interesting video! I didn't know that mipmapping works on literally the same principle as the Lod system. There is an option to adjust mipmapping in cs 1.6 too, I thought all it did was smooth out textures so they didn't look so pixelated

That railway zoom out explanation was excellent.

Note: Enabling Mipmaps will use more GPU RAM since so many textures have to be uploaded onto the GPU it will fill up your GPU RAM.

Thanks for the video!

Keep this great content.

You learn something every day, thanks and great vid!

What a intresting idea for a video instant ly subbing

Awesome explanation!

What i find to be the most hilarious little setting in the PC port of GTA SA, it's how weirdly heavy its Anti-Aliasing implementation is still to this day... Even the awful GTA IV PC port didn't have such an advanced tech.

Thank you for your video I just want to know what is mip mapping Very useful 👍

Excellent explanation, thank you

Very informative..thanks for sharing

thank you, nicely explained

I first figured out what mipmaps were when replacing AC2 textures. Didn't know texture crushing was the name for it

Thank you Sir for This video

Great explanation thanks

Man, there goes 11 years+ of PC GTA experience without knowing about that... omg tysm. I'm now finally enlightened.

Great explanation.

Carl Mipmap Johnson

so basically realtime resizing vs baked resizing

"What is Mipmapping in San Andreas?" This applies to any game.

This game is beautiful to this day.

perfect video

Recommended video and I like it but the problem is mipmap thing is disabled in my game and I’ll have to find ways to enable it Btw, can you tell me why shadows of objects doesn’t appear in my game even though I tried some mods too but didn’t work for me any idea how to solve it? Any help would be appreciated :)

I can't stop looking at the way the gravel of the train track texture was extended. It's not that hard to copy a part of the texture other than the area right next to it

bro canyou made a guide for mixsets ?

Hey bro, make a video on the 'Enhance Particle TXD' mod for GTA SA

If you were to display the game on a screen with such a high resolution, that even in the most zoomed out view, the screen area occupied by the high res texture contains enough pixels to show everyone of the 1 million+ pixels of the texture, would this eliminate or combat the need for mip maps?

Its so strange that something like Nanite for geometry took decades after invention of mip-mapping and virtual textures, why such a huge gap?

I'm squinting at the 360p footage on my phone screen as hard as I can to see the differences.

Does mip mapping only apply to the location of the player, or does it apply to the camera? For example, if you are looking at that train track from the sky, the resolution will be lower. But what if you zoom into that train track with a sniper rifle? Will the resolution still be low, as the player is far away? Or will the texture pixel quality increase the further you zoom in with the weapon?

I find difficult to like some implementations of mipmaps because of the lost sharpness and details

What if we turn off mipmaps but also use Anisotropic Filtering 16x? I like the extra sharpness of the textures, but not the aliasing. Maybe AF can fix that, and a bit of ReShade TAA+FXAA+CAS. P.S I also noticed that the mipmaps can never be turned off using the game settings, When I was much younger, I kept checking multiple times for maybe hours trying to find the difference between on and off lol.

Muchas gracias vato que habla ingles :D

It's like LODs for textures. Got it.

Yup, from up hoigh the soize of the texture is mooch smaller indeed.

Ima be real I love the aliased noisy look lmao

Forgive me for having a hard time discerning noise in dirt texture… 😂

How to export a texture dds with Mipmapping?

I thought mip mapping was the hands I put on pedestrians on the street

Could this be that at 8k render resolution you shouldnt need mipmaps? At that res i imagine you wouldnt need to downscale textures even at great distance

Mipmapping is all great and good... as long as there's a method to adjust anisotropic filtering.

So.. image gets sharper (when the option is *off*)? :j

This video explained the concept very well, but there is one thing though, you forgot to talk about the performance impact. I never bothered to look into it, and so I thought I'd find it here. I'm pretty sure it is negligible, correct me if I'm wrong.

i mean, the noise makes it kinda realistic at certain point a think less of the original would be great because theres too much, but in the mods theres 0

This sounds like the LOD for models. The way it works.

You take the understanding of GTA SA to a scientific level. lol

basically lod for textures

If this is mipmap, what is antialising for?

if mipmapping is disabled how can the computer process all those millions of pixels at 60fps?

hi mate - whenever i play my modded game, it crashes at random instances - driving, or walking, or standing, or entering an interior. theres no warning. usually happens after playing for 30mins or so. i tried reinstalling, remodding and testing...i dont know what the problem is. any ideas?

Didn't you make a pack with all San Andreas Textures Mipmapped? IIRC Rockstar forgot to mipmap some of them in the texture and it looks pretty terrible. Especially on the PS2 version.

damn i always just turned it off because i never saw a immediate noticeable sign

What is anti aliasing

When I disable TAA smoothing in modern games textures become noisy...Modern games have no mippmapping?

Is it bad that i dont see a difference in the comparison shots 😅

W vid thx for the explanations

“Extreme”

awesome video

This and some of the other settings in your other videos seem awfully important, but I've never seen them in modern game settings. Maybe they are enabled by default or have more optimal solutions under the hood nowaways?

After watching this video, I'm just a bit baffled that mipmapping decreases performance and doesn't increase it. How is that possible if it so significantly reduces the resource requirements of each texture? Is the on the fly replacement really that expensive?

1:26 why'd you blow up ryder's car?

i like it minus the shimmering

3kliksphillip of gta

short answer is : mipmapping creates temporary versions of any texture with multiple different resolutions the further a texture is showing, the lower it's resolution sample is !

I only see a difference when moving

So its like LOD but for textures

explain to me why EVERY game drops down to 15 FPS on my AMD rig when MipMapping is enabled? GTA San Andreas? Phantasy Star Universe? Minecraft Java Edition? even fukken Cyberpunk 2077? I could run that on 122htz freesync on very high settings, but turning on mipmapping, the game drops to a slideshow on low setting with shadows off and forced FSR on ultra performance

i honestly quite like it with no mipmapping

ur pfp looks like it needs mip mapping lol

I like it without mip mapping

an early lod

i like it more when it is turned off

irish lisp goodness

I really want to play gta sa again but we lost the disk long time ago and asshole rockstar removed it.

meep mapping

Loving your Schwarzenegger accent

So its basically a LOD

youtubes compression really ruins the point

i love how modern games dont have problems with texture crush but model crush making them look terrible Lmao
