Real-World Example: Gaming Scenario
Scenario: You have 8GB RAM and want to play a modern game that recommends 12GB.
What happens:
- Step 1: Windows 11 takes 3GB RAM for OS
- Step 2: Game loads and needs 10GB RAM, but only 5GB available
- Step 3: OS pages out some Windows system services to hard drive (creates 4GB free)
- Step 4: Game loads into 9GB RAM + 1GB virtual memory (runs, but stutters)
- Step 5: When game needs that paged-out data, OS swaps it back (causes frame drops)
- Result: Game runs but with lag spikes every few seconds - playable but frustrating
Solution: Upgrade to 16GB RAM. Virtual memory is a backup, not a replacement!
