I've noticed that the SLI Sync and Voltage Limit sections are at 0 when I'm playing normally but when I start to stutter they fluctuate to 1, what are these things? Also my gpu usage seems to be higher around 50-60 with no stutter and around 35-43 when stuttering.

Here's a link to my MSI afterburner HW monitoring file. (ZIP file one when stuttering and one when playing normally, Virustotal link, no these files are not a virus)

The game played was CS:GO, and also the sudden drops are when I use the SHIFT TAB feature in game or when I tabbed out to my desktop. I can get a more "stable" monitoring file if you guys need, with me not tabbing in and out.

Specs:
CPU: Core I5 3570
MOBO: MSI H77-G43
GPU: EVGA GTX 950FTW
RAM: G. Skill Sniper 16GB
Storage: Crucial BX100 120GB, 1TB Caviar Blue, 2x Seagate 500GB SSHD
PSU: EVGA 650 GQ
Cooling: Hyper 212 EVO

I'm wondering why you have a readout saying "SLI Sync", when your specs indicate you are on a single card. I would target that as a possible source of your problem. Seems like maybe a fresh driver install is in order.

Edit: I just checked out my Afterburner and I see that you can enable the SLI Sync graph on any system. You may be having more of a voltage problem then. It should be rare/impossible to hit that limit when playing at stock settings. What are some of your other readouts, GPU usage, Temp Limit?

SLI Sync and Voltage limit are performance limits basically. For both of these 0 means "False" and 1 means "True". So when you get 1 for either of those it means you're hitting the limits. SLI: this is basically saying that what is limiting your performance is the SLI transfer rate. How quickly they can communicate and render frames. Voltage Limit: Essentially the card is running at the max voltage allowed by your GPU BIOS and this is limiting it from higher power outputs. Not a bad thing something has to be a limiting factor otherwise you would hit infinite frame rates. I don't know why the Steam overlay causing stuttering.

Update: One thing I read was if you use the FPS counter overlay that steam offers that can cause stuttering. So disable that if you use it and that can help.

I dont use the fps counter, and also I'm on a single gpu which makes this strange. Also the tabbing isnt a issue I just stated that because if you look on the graphs there is a sudden drop and I just wanted to make it clear that, that was just me tabbing out. (so gpu and cpu usage should drop, and you should ignore those parts)

So yeah I am on a single gpu and I don't wanna ignore the sli limit completely BECAUSE there is a change from when I'm lagging to when I'm not lagging. Like stated before "I've noticed that the SLI Sync and Voltage Limit sections are at 0 when I'm playing normally (no stutter) but when I start to stutter they fluctuate to 1".

Also like stated before, the gpu usage on avg (in csgo) is around 50-60 but when stuttering it drops to around 35-43. Please try downloading my hwmonitoring file and take a look on after burner. (As I cannot name ALL the statistics)
