I don't have any new magic if as you write no one has a fix.
I like to check the Speccy and Userbenchmark reports to see if there's more to try but is this a new issue or is the machine new? Once in a while I'll get a two year old laptop that the owner didn't know about canned air use.
Or they don't know to tinker with game settings (lower them) till it works. Some games may work out of the box (or install) while others require a lot of adjustments.
Dark Souls 3 has FAR TOO MANY COMPLAINTS. https://steamcommunity.com/app/374320/discussions/0/133256758573312716/?ctp=1 does note that during invasions/teamplay so it may be just too heavy a game for some machines.
Hi, I'm having problems in certain games where it'll start out fine but then start lagging severely in 4 second intervals, a very regular stutter. It's only in some games, like Dark Souls 3 which makes it impossible to play, but not in other games like GTA 5 which requires high performance but still works fine. I've looked up solutions and seen a lot of complaints about Alienware 15 R3 (my PC) lag, but no solution that works. It could also have to do with Windows 10, I just don't know. Hit me with any thoughts or solutions, and let me know if you need more information. Thanks!
