I recently built my first computer intended for gaming(converting from console). That being said I am still relatively inexperienced with computers.

I am getting lag spikes that last a few seconds in Minecraft. Vsync is turned on to limit fps to 60. There is no pattern that I have noticed when they happen. Sometimes I get a couple in a minute, and other times I can go 30 minutes without one. Here are my computer specs:

OS: Windows 8.1 Pro
Motherboard: ASRock 99FX Killer
CPU: AMD FX-8350
Memory: G.Skill Ripjaws Series 8GB
Video Card: MSI GeForce GTX 780
Power Supply: EVGA SuperNOVA 650W 80+ gold certified
Storage: 2x Samsung 840 EVO 120GB in Raid 0

Some pictures of the lag spikes. These happened before I had optifine installed, just installed it to get a visual of the lag spikes.

This problem is only limited to Minecraft, as I have played many hours of Skyrim on the same PC with no issues. If you need any other information let me know.

Thanks in advance

Download and install "Geforce Experience", and update your driver. If its "up to date", then give the newest beta driver a go.

It might also be the game thats causing it.
I'v played loads of games where i have 100fps ++ at all times, but i still gets spikes every now and then ( Somthing i'v experienced on multiple pc's). And that commes from the poor coding they have used when making the game.

Haven't played Minecraft in quiet a while now, so can't say for sure it Minecraft themselfs has messed up some of their coding during the later updates of the game or not.

If you look at the pictures he uploaded, you can see that the ram is still at 40% use, even when it spikes. So that doesn't seem to be the issue.

1 question for you Gardner2011, does this happen in both Single and Multiplayer? Or in multiplayer only?

Sorry for the very late reply to this, but I got busy with school. Back to playing now and still having the issues. It happens in both Single and Multiplayer.

Pretty much every game out there, still only utilizes 1 cpu core. Converting and video rendering, 3D animating and alot of other multimedia software are close to being the only programs that uses more than 1 core.

And saying that AMD cpu's will give performance issues if only 1 core is used is somthing only an Intel Fanboy would be arrogant enough to say.

I run all my games, such as CoD Ghosts, Battlefield 4, Final Fantasy XIV, World of Warcraft, Crysis 3, FarCry 3, Elder Scrolls: Skyrim, Elder Scrolls: Online etc etc, at 4K resolution and high preset (some games with AA at max) using an O.C AMD FX 8350 cpu, and my cpu has never been bottlenecking the performance of a single one of those games.

Cold hard facts is that Intel's cpu's deliver MORE (stronger) performance pr core. Just because Intel can deliver more does not automatically mean that AMD's can't deliver ENOUGH for gaming (which they do).
 


I'm not sure if you're aware, but BF4 uses 8 cores, WoW uses 2 cores, Crysis 3 uses at least 4 cores possibly more, FC3 uses 4 cores, and Skyrim uses mostly 2 cores but uses another 2 slightly.

You really want to test this? Download a program like CAR, disable all but 1 of your CPU cores temporarily. See if there's a difference in games. I promise you, you won't get above 20 fps in BF4 with 7 cores disabled.
