Just to get the board up to speed, it seems Win10 memory management, specifically how Win10 handles "standby memory" (think superfetch for faster OS and apps) causes stutter in games.

The issue seems to be that while Windows 10 is great at filling RAM, it's really bad at dumping memory for application use.

The bug occurs when you no longer have free RAM left.

For example when Forza uses 8GB, and your remaining 8GB is standby (superfetch) data, Windows 10 completely mismanages this situation, failing to dump the standby memory to allow further game assets to be loaded. Instead what happens is the OS constantly fights to keep the RAM filled with standby data, causing noticeable hitching in any game that is running, as long as your combined active and standby fill your entire RAM pool.

This can happen in any game, and as far as I can tell this will happen on every single Windows 10 system with 16GB of RAM under conditions where the system has been on long enough to accrue a large standby pool and you're running a game with a large enough memory foot print.

There's been a lot of noise made about stuttering since the first Creators update, which has continued with the Fall Creators update. It seems the brunt of all stuttering issues since Creators have been down to this absolute disaster of a change to memory management in Windows 10.

And I repeat, it seems it affects all systems with modest amounts of RAM, but could probably be induced on 32GB systems if you tried hard enough. Most people don't seem to notice the stutters, but G sync users have been able to spot them much more readily than everyone else. This lead to everyone believing the problem was with G sync, but it isn't, we're just the canary in the coal mine for a rather significant software engineering issue at the moment.

Not all games are affected equally. Some titles, like Assassin's Creed: Origins rarely exhibit the problem on a 16GB system because they're fairly memory light. It's very much dependent on how large of a memory footprint the game has, how long your system has been on for, and what apps and installation processes you've run since last boot. For example Steam game installation files will be put into standby and induce this issue extremely quickly.

Finally, the issue is confirmed because clearing of standby memory completely resolves the issue. The problem is 100% reproducible and can be resolved using a piece of software called RAMMap.

So in short in order to 'mitigate' this particular issue until MS comes up with a more permanent solution is to restart the PC frequently?

There's a really neat trick that solves pretty much all the problems that come with Windows 10:

Use Windows 7 instead

You are supposed to not give a f*** and buy the most overpriced under specced prebuilt available and gloat about the new Windows OS.

Rammap has been around for a very long time because windows has had this issue long before Win10. This is why people who tend to leave their computers on for ages get less performance in a lot of things than they should, but end up not noticing cause they never restart their system. So the reduced performance is their norm. And often, Rammap does not clear correctly, and the system must be restarted. I've noticed it on my own PCs, WIN 10 desktop and Win7 laptop.

OP I had that same problem with Win7 with a lot of games...but ever since I switched to Win10 I don't have it anymore.
