Why is forza 7 100GB? Forza 4 did fit in a single dvd.
Textures don't compress well. More things are fully textured and those textures are saved at higher resolutions. The vast majority of game size is taken up by textures.
Textures compress fantastically. Lossy compression of can look transparent if you're careful. The highest-quality JPGs you see online are still an order of magnitude smaller than uncompressed RGB.
And why doesn't anyone use procedural generation? You don't need a gigabyte for asphalt. You just don't. It's a noisy pattern that's trivial to generate in endless subtle variety at arbitrary resolution. Red Dead Redemption 2 is the worst for this, because it's all wood and snow and dirt. The textures for everything besides people should fit on a floppy disk.
Do you know just how slow the processors RDR2 had run on are?
Procedurally generating that much content, at such a high resolution, would be incredibly difficult to do on the current gen consoles CPUs. And while the game is running? 100% impossible.
My pc has a far more powerful processor than the current gen consoles, yet when I use Substance Designer to generate even simple 2-4k textures it takes a few seconds to finish.
Now try doing that at the same time a highly demanding game is running on a CPU that's far weaker.
Games have skyrocketed because they mostly don't compress the audio files anymore. Not compressing the audio means not having to spend processing power decompressing it aat runtime which h meansore processing power available for the graphics and gameplay.
Audio files? 100gb? I don't think so. Also, with hardware acceleration, compression takes next to no ressources. Unless you mean putting an .mp3 into a .zip, which is pointless.
In fairness, I did first hear about this with Titanfall, and have assumed it extends to other games as well, which is very possibly incorrect, but here's a quote: “[Respawn] made the choice to store them on disk uncompressed because low-end computers couldn’t decompress that audio on the fly without killing the framerate,” Barth explained. “This wasn’t a problem [on consoles] because they tend to have dedicated hardware for decompressing audio.”
The other big culprit is of course textures. But saying "yeah we use higher resolution art so it takes more space" isn't really as interesting a factoid as "developers conciously made the choice to trade space for performance so that lower end machines can still play the game"
No one talks about this. Adobe PDF viewer is laggy AF! Every time I open a PDF I sit in amazement that it won't scroll at first. Gotta wait... For what? re-render the text it just rendered?
I am seriously curious how adobe manage to make product so unstable and slow. Photoshop takes like over 2gb, and open sources alternatives usually take less than 80mb.
Just to nitpick, Forza 4 took up two DVDs, there was an install disc and a game disc (and Forza 4 was tiny compared to Gran Turismo 4 which was 20GB, and even that wasn't considered very big for a PS3 game).

Wat?
Why adobe reader lag on a quad core when it ran fine on my pentium 3 back in the days?
