GTX 970 Frame times, STUTTERING, low GPU usage, Source games mainly affected (CSGO, Dota2)
  2 / 5    
[quote="Sora"]Source doesn't scale to all cores, nor is it really very heavy load on current gpu's. Your CPU is bottlenecking you. Resulting in your GPU load being minimal at whatever FPS you are getting. Resulting clocks returning to low power 3D or 2D. Reasons for stutter could be anywhere, but its most likely that the game is falling back to 2D clocks and suffocating the vram performance.[/quote] Sounds correct, so why can't I force clocks to remain high? Also I've checked the clocks whilst playing Source games, and they remain high constantly. Putting a GTX 660 into my system yields MUCH higher FPS... I tried every maximum power mode available, they don't do anything...

exactly the same here, gtx 970 and 100-250 fps in cs go, all the nvidia support has to say about my ultra detailed ticket is "enable vsync" <- TO PLAY A SOURCE GAME THAT RUNS ON EVERY POTATO ON A 400$ GPU what a joke Edit: my gpu usage in cs go is @ about 30-50% and I have 10gb of gddr3 ram, I dont think thats the problem especially considering I had more stable fps with my old amd radeon hd 7770

Here is my Afterburner graphs while playing a 10v10 Deathmatch, keep in mind, if I am CPU bottlenecked here (which I actually don't think I am since I got higher frames with a crappy GTX 560) during a 5v5 which I normally play, the CPU usage doesn't come anywhere near this. http://imgur.com/a/7VhBh The dips at the start is the map loading, the dips at the end of the graph is where I minimized to take the 3 screenshots As we can see, the clocks never clock down unless loading a map or minimizing the game. Any ideas? @vermillioNx, exactly.. run vsync so we get increased input lag and are put at a disadvantage. Vsync in a game like this makes no sense when I have a 144mhz monitor. This is a joke and if it isn't fixed by the end of the week I'll be sending this card back to Amazon and going AMD, never touching nvidia again.

Very true, we're just being kept in the dark, meanwhile they are releasing drivers for fixing nvidia laptop errors... while this GLARING ISSUE with their flagship product remains. Here's some more Afterburner charts with polling rate every 200ms instead of 1000ms to try and pick up the microstutter, nope.. all rock solid. http://imgur.com/a/FANF2 Good job the 290X is on offer atm.

lol I even just underclocked the GPU as much as Afterburner would let me so it uses more GPU usage, still a stuttery mess... every other game but Source engine games are great thought so that's something right? looool

I'm going to ask a friend to let me remote into his machine for a bit and take a look at processor loading, there is no particuar reason for stuttering or low fps if the gpu is remaining at 3d clocks. There is possibly api or driver overhead at work since D3D9 is more or less converted on the fly to work on unified shaders.

something else is causing it, it is not a GPU or NVidia drivers. I am running CS and CSGO on all my three rigs perfectly fine without suttering with my 980's. what CPU, memory and motherboard you have?

Scratch that, I tried my brothers 660 in my rig again just now and the stutter/low fps was still there. I then disabled XMP RAM profile in BIOS and just set it manually to 1333mhz and my FPS has been a lot higher, hitting the 300fps cap now consistently, although stutter still remains that wasn't present before... oh well :\

My old dual core Celeron with a a Radeon 7770 or GTX 760 was able to get better performance and Gigabyte G1 cards that turn off the gimmik power saving feature of Maxwell are fine.
