I worked on a PC/PS4/Xbox One game once. I wish I remembered more details, but at some point when looking at memory usage I found a 2048x2048 (or something like that) texture for something on a character. This texture was never anywhere near occupying the full screen. It got downsized once I told one of the artists, but I wouldn't be surprised if some games are inadvertently shipping with that kind of waste.

The release version of City Skylines 2 had enormous issues due to this problem. Some tiny details, like a pile of wood behind a shed, had ridiculous amount of pixels. I do believe that should be pretty much fixed in that title nowadays, however.

wasn't it rendering every pedestrian's teeth in detail as well? hilarious oversight

I gave myself 32GB of swap since SSDs are quite fast and the pages sent to disk seem to intelligently be rarely referenced ones. Feels amazing to run 4 VMs and 12 Claude Code instances on my mid tier hardware

Swap doesn't help in this case. It's GPU drivers freaking out when they run out of VRAM, but it might only be specific to NVIDIA cards since AMD seems to handle this better. But, if it's driver specific that means it could be fixed at the kernel level I suppose, especially since Windows handles it seamlessly?

Can you explain a little more please. I thought that graphics processing would revert to CPU if the GPU is maxed out and so swap might ultimately help? Is there no general GPU-swap mechanism? If CPU threads are competing for GPU resource does the GPU getting paged-out?

I suppose this could be an historic thing, GPUs can have a type of DMA now, and disk access is much faster too, so paging perhaps makes sense when it didn't before?

Gosh, 7.2 literally just dropped with a bunch of awesome of performance/gaming related improvements (large folios, cache-aware scheduling, improved MGLRU reclaiming, Fair GPU Scheduler etc)... and I already can't wait for 7.3 to come out. Meanwhile in the Windows world, users hate updates... Like I genuinely can't think of a single instance that made users exclaim, "oh boy I just can't wait for the next Patch Tuesday…

I use arch based linux. This year updates have broken video decoding twice. Font rendering once (still not fixed without manually deleting files.). And broken the whole system due to there not being a mechanism that makes sure all QT libraries upate at the same time once or twice. That is all one system.

Meanwhile 4 separate windows pcs have not had problems with updates for at least 6 years

I'm mostly excited for the VRAM savings from apps and games which have loads of unused or super rarely used textures. Game developers often aren't super careful with this stuff, and there could be literal gigabytes of data which isn't used at all.

Are there any people out there doing this optimisation post-release for existing games ?

I personally am very excited for the upcoming Windows 11 update which will allow users to move the taskbar to any edge of their screen.

Ah it'll be just like 2015 again

Yep and it will be glorious.

I cant wait for the number one gripe of all my users to finally be catered for.

Any improvements with fractional scaling? Can anyone please link to any material reg the work being done for improving fractional scaling in Linux; it would be great if it could match the rendering quality of macOS.

What's your setup like? I'm on AMD+Wayland+KDE, no complaints with fractional scaling on my ASUS ProArt PX13 (255 PPI screen).

I don't use windows too often, but I remember I was happy with an update a year or two ago which allows changing the volume by scrolling on the tray icon.

Now, of course, it still doesn't work with a touchpad, but baby steps, right?
