Answer #3
the problem? Running 2 games at the same time.
Graphic? Which one. 2gb means nothing, there's dozens of cards
i7? Which one, there's dozens of cpu's
CPU : Intel Core i7-3770 CPU @ 3.40 GHZ
GRAPHICS (GPU) : Nvidia GeForce GTX 650 Ti Boost – DDR5 – 2GB (324 Mhz)
Memory : 16 GB – DDR3 (Dram Frequency: 798.1 Mhz)
Answer #4
My guess, the GPU is strong enough to handle 1, but 2 bottlenecks the VRAM, then there’s the issue that you’re running sandboxed which introduces lag by itself and 2 games, that’s just a bad idea. Your cpu is powerful, i’d say your GPU is the bottleneck. It’s even older than my current GTX 680.

You are running Siniper Ghost Warrior twice?? WHy? and How?
Answer #6
You can not run egoshooters or alike hardware hungry Games in a “virtual OS” like Sandboxie and expect no lag.
