Virtual cores, also known as hyperthreads or logical cores, are a feature found in modern CPUs (Central Processing Units) that allow a single physical CPU core to handle multiple threads simultaneously. Each virtual core appears as an additional processing unit to the operating system, even though it shares the resources of a physical core.
This causes performance issues for most games because it splits one CPU into two.
