If your PC isn’t performing as expected despite a powerful CPU and fast graphics card, the RAM might be the culprit.

You can check for a RAM bandwidth bottleneck directly in Windows 11 by opening Task Manager (Ctrl-Alt-Del) and monitoring the ‘CPU’ and ‘Memory’ sections…

GeForce Now is a pretty good solution for PC gaming if you’ve got a big game library, but want to access it remotely, or just without high-powered hardware.

But what if you want to access it without giving Nvidia control of every part of the experience? Say hi to OpenNow, an open…

It probably isn’t whether or not it’s a security risk. But a newly developed attack uses the super-fast memory in a GPU as a means of gaining elevated privileges in Windows. Security researchers at the University of Toronto were exploring the…

But can gamers avoid paying out outrageous sums of money to keep up? Texture compression might be an answer, shrinking down the size of games as well as allowing them to fit into the limited video memory of older, cheaper cards.
