-
Anil Harwani and Pranav Dani talked about OS modes to justify the reasons behind not installing Valorant on local devices. OS runs on two modes: The User mode and the Kernel mode.
-
Processes running in kernel mode have unrestricted access to the hardware. Processes running in user mode have limited access to the CPU and the memory.
-
Most applications run in user mode, and core operating system components run in kernel mode.
-
Valorant asks for user permissions to attach itself with the kernel mode to verify the device and "prevent cheating" during online matches.
-
Since the game drivers have kernel mode access, they can potentially send any data about the local system to its servers that could not be trusted.
