While the operating system can dynamically allocate gigabytes of additional system RAM (known as "Shared System Memory") to the iGPU as needed during gameplay, many modern game engines do not understand this dynamic allocation. During the startup sequence, the game queries the system for dedicated VRAM. If it detects only 128MB instead of the required 2GB or 4GB, the game will trigger a fatal error and refuse to launch, even if the PC has 16GB of total system RAM available.

Integrated graphics processors (iGPUs), like Intel HD, UHD, or Iris Xe graphics, often struggle with modern gaming and resource-heavy software. The primary bottleneck is not always the raw speed of the chip, but the lack of dedicated Video RAM (VRAM). (Note: As always, scan the file with VirusTotal
