Question / Help In-game lag

[Malte Schulz]

So, i've now been streaming Counter Strike for 4-5 weeks, without any problems. but a couple of days ago, i started my stream, and suddenly my game was laggy. I couldn't figure out how to attach files, so i've put 2 links in the bottom to screenshots of my Net_graph, where as you can see, nothing really changed after i started my stream (First picture is off-stream, second is on-stream), so i don't really know what the problem is

Here are my pc specs:

Cpu: Intel i7-4770K, 4 x 3.50 Ghz
Cpu Cooler: Antec H20 620 watercooling system (Does not require maintanence)
Gpu: 2 xASUS GTX 660 DIRECT CU II Edition, 2GB, OverClocked! (750 PSU)
Ram: G.Skill RIPJAWS Gaming 2x4 GB DDR3, 2133 Mhz
System disc 1: Samsung 840 Series 120GB (Ssd)
System disc 2: Some random 2TB one that i don't remember the name of
Motherboard: MSI Z87-G45 GAMING Killer NIC CFX/SLI Military Class III

If anyone can help me fix this problem, i would be really gratefull :)

Just a side-note: Figured out why i couldn't attach the files. They can be maximum 1MB, and my files are 1,03 and 1,05 :P
