But honestly it is not so bad for games,  Don't take 4k movies around 100 GB? I remember one of the first 4K movies surpassing 150 GB.

Netflix streams them at around 18 mbps with HDR, that's 7.9 GB per hour or 16GB for a 2 hour movie.
4K UHD discs can hold upto 100GB Not all of that is for the movie as it includes multiple soundtracks and extras.

The first 4K movie was 330GB for a 52 minute movie in 4096x2304 12 bit cineform format.

4K UHD is still very lossy compressed compared to that, that file runs at over 800 mbps, compared to max 128 mbps for 4K UHD discs.

It wouldn't be so bad for games if they came on 4K UHD discs, and installed to a 2Tb SSD drive :)

At some point we may truly get to sound and pixelcount that is already "all we need"

The new Pixeljunk VR game Dead Hungry is 545 MB, there's probably smaller than that. Yet a 100GB game must be 200x more fun!
"All we need" is still very far off. Proper full spectrum holographic video is still sci-fi.
Plus we need gigapixel textures like these https://www.theverge.com/2016/5/17/11686296/art-camera-google-cultural-institute :)

It ain't fun until you can zoom in on the dust particles on the walls. (looking at you gts, modelling air vents in the car interiors... you got me, that's what I'm looking at while racing)

On topic, why be unhappy when you actually get to see a real difference. When I got the ps4 pro, try as I might, I couldn't see much difference between between downsampled and normal 1080p on a 1080p projector. At least with the X you should still see some actual benefits on a 1080p screen from improved textures.

For games Gears 4, Halo 5, Halo:MCC, and Forza titles, I kinda understand it. Those are games with tons of content.

But Quantum Break is a short campaign and no other content. The FMVs aren't even included in that 100GB. While the game looks above average the assets aren't mindblowing. I don't understand why that game is so big.

Sure the size doesn't mean enjoyment. And sure it can always improve... but I was talking about sound quality and pixel+IQ (sure raytracing and even more advanced will take even more)... but for regular people it is quite close already.

Sure I just remember those lists back in the day it is hard to find them like this one for example:


It is all confusing because I see people discussing that some aren't really 4k but are upscale to 4K etc.

Actually raytracing will take less. No more need to bake in global illumination which is what's bloating games like AC Unity, Forza and GTS. For sound quality, there's a chance that will be the next bloat as ray casting for physics based sound reflections will probably first need the same pre-bake solution as global illumination is using now.

Whether the source is upscaled or not doesn't really matter.
Consider this, uncompressed 8 bit 1080p24 video runs at 1139 Mbps, compressed down to avg 25 Mbps on blu-ray, 2.2%
Uncompressed 10 bit 2160p24 video (4K UHD) runs at 5695 Mbps, compressed to avg 50 Mbps on 4K UHD, 0.9%

Both blu-ray and 4K UHD half the bandwidth before compression with 4:2:0 chroma subsampling, discarding 75% of the color information (only the color of 1 out of every 4 pixels is stored). So even if the source was upscaled to 4K, you still get 4x the color info compared to blu-ray, plus 4x the range with 10 bit per color. Both can't resolve fine detail in action scenes with that high compression factor.

Video games give you full fat 10 bit uncompressed output at 60fps which is 14,238 Mbps, or 13.9 Gbps. So sure, higher quality assets and bigger file sizes for games aren't so strange. Comparing graphic fidelity of video games through you tube videos, that is kinda pointless nowadays.
