selection base on PC spec

[Airuz]

please add a new feature where Steam can detect PC specifications such as CPU, RAM, Storage
and can provide game recommendations that support our PC and have an alert if the game is too heavy to run on the client's PC

for example, The minimum RAM for "this" Free game is 16GB. but if the user's PC only has 8GB RAM, Steam will give a warning before the player can download the game to avoid having a bad user experience with the game even though the main problem is not the game but the hardware.

and there are also recommendations for games that support the user's PC specs to avoid buying expensive games with high specifications. Still, the hardware is not adequate to play the game, aka money wasted on games that can't be played.

That would require spyware that Steam won't use.

How would Valve evaluate any of the following requirements:
System requirements: Potato. / Potato+ / Practically runs on a potato. / Extra shiny potato pro. / For those who like to bake their own potatoes just the way they like 'em.
OS: Windows 9000000
Processor: Sure
Processor: yes
Processor: The metal part of toaster when it's being heated
Processor: Post 2010 CPU
Memory: 999 GB RAM
Graphics: Thing that heats the metal part of toaster
Sound card: Something that makes noise (Recommended: Something that makes pretty noises)
Sound card: One that can handle extreme loudness
Sound card: MAXIMUM VOLUME YIELDS MAXIMUM RESULTS

How about these:

The system requirement area is a pure text box and, as you can see, the developers can write what ever they like on it.

Refunds exist (among other reasons) so you can figure out if a game runs on your computer if you're not sure.

Odds are, unless the system requirements point out a specific technology you need (like AVX2) and your processor doesn't have it, you can run the game, regardless of what the system requirements text says.

Like many of these threads, even those do not take into account the entirety of the systems current status as of the moment looking at requirements vs where the system currently is.

For example if you need 16GB but have 8GB, it can likely work if the game doesn't need an SSD, however, if you have very low storage space remaining any written data could cause critically low resources resulting in terrible performance, crashes, or BSODs. That is just one thing it can't take into account, let alone others.

Best to just be aware of where ones system is vs min/rec specs, and if someone still has 8GB it's time to have at least 16GBs though these days I recommend 24-32GBs of RAM.
