Bizarre 100% CPU Usage Mouse Movement Issue
An example of the mouse movement issue that can occur when hitting 100% CPU usage on Coffee Lake CPUs (in this case a Core i5-8400) in 3D games. Origin and Oculus processes seem to be involved in the issue (despite having low CPU usage) as changing their priority levels has a significant effect on the mouse behavior from completely eradicating to totally exacerbating it. Here, Shadow of the Tomb Raider and Prime 95 are used to demonstrate the mouse movement issue, however I've also experienced it in other processor intense games such as Battlefield 5 and Assassin's Creed Odyssey. Similarly, while the Origin.exe process is focused on in this video, the OVRRedir.exe process (Oculus) exhibits identical behavior. In fact, sometimes both Origin.exe and OVRRedir.exe have to be treated before the issue goes away. While it's tempting to point a figure at the processes themselves, I believe the root of the issue is deeper than that. The issue may be potentially related to Coffee Lake CPUs or just higher-core CPUs in general as the issue doesn't seem to occur on older quad core hardware. Fresh install of Windows. All Drivers up-to-date. Multiple mice tested. Multiple motherboard tested. All PC performance vitals (CPU, RAM, GPU, Disk, Temps) are within range, with the exception of the CPU which is of course being intentionally stressed to demonstrate the issue. If I were to take a stab in the dark, my hunch is it's a Windows kernel-level bug with thread scheduling. If anyone can shed light on this issue, it would be much appreciated.
