Frametime isues?

[JuztBe]

It happens quite often while gaming. FPS in game doesn't really change, but it feels like stuttering. Could it be becaues of frametime? And fromwhat frame time does actually deepens. VRAM maybe?
And GPU utilization, what does this mean?

Looks like you are on a laptop?

 

Could be throttling.  Try and turn the fans all the way up.  Maybe buy a cooling tray for the laptop.  Get some airflow over your laptop.

Heyyo,

 

Frametime variance? Linus explains it perfectly in his SLI video...

 

 

Right around the five minute mark he explains frame time variance / micro stutter.

 

Essentially? The more of a gap you have between minimum framerates and average framerates? It'll create unsmooth animations causing micro stutter.. Frame time variance is mainly an issue for multi-GPU setups..

 

GPU Utilization? That's how much load is on your GPU, much like CPU useage.

 

 

Here's an example of me using MSI Afterburner in World of Tanks... you can see my GPUs are not being maxed out... My GTX 680 2GB in SLI is only using about half the GPU load, shared across each GPU... My 16GB of RAM isn't being challenged either with the game being 32bit and limited to that 4GB limit... my CPU on the other hand? Damn this single threaded game! only ONE of my eight GPU...

 

But the good news? My frametime variance is only 19.7ms, which is really good! Essentially? As long as the frame time variance isn't above about 40ms? It'll look smooth... but jumping between 19.7ms and 40ms or higher? I'll visually see stuttering as my GPUs struggle to deliver as smooth of framerate as possible to my monitor.

 

Here's another prime example... The stuttery mess that is Final Fantasy XIII-2 port to PC (same goes for FF XIII) and the guide I wrote about why forcing a 30fps limit fixes the stuttering due to a lower deviation in frame time variance due to how the game constantly tries to flop between 30fps and 60fps frame rendering...

Hope this helps.

 

 

Oh, and for VRAM? You ALWAYS want to have your settings to a point below the amount of VRAM your GPU has. Otherwise? It'll cause more hitching and stuttering as it constnantly tries to load too much data to your VRAM and keeps going in a circle reloading information which will cause your framerate to tank and cause serious frame time variance. So? Your notebook should be the GTX 750M 2GB edition... Since it's only a GTX 750M? Odds are the GPU will have problems running before the game fills the VRAM banks... so your best bet? Lower resolution, anti-aliasing or model detail levels as they will cause the most load on your GPU.

It's 4GB version. 

I have replaced thermal pads today. Maybe they are not thick enough and chips doesn't contact well with radiator, could that be a problem?

EDIT: It's not on every game, looks like thermal pads are fine.

Heyyo,

What kind of temps do you get when you game?

Which games are acting up?

Up to 85 degrees. And it's path of exile and life is strange. Dying light is fine tho. Reduced couple settings at POE, much better right now.

Damn! that's toasty if you mean Celcius. Try dusting your PC?

 

Have you tried MSI Afterburner as well? It'll help you figure out what's causing your grief. My guess is you might be running into thermal throttling with 85 degrees.

 

Another thing? I'd recommend VSYNC for Path of Exile. Since it's an isometric game? There isn't a lot to render on the screen at once. VSYNC at 60fps won't stress your system nearly as hard. Just enable triple buffering with it to keep the framerate as smooth as possible.
