99% Load on GT540M

[SilentHorizon]

Hey all! I believe this is an issue with optimus technology. Since from what msi afterburner reads me, the gpu never goes up to 100% load, only 99% and under.

Well yea its not gonna hit 100%; does it matter? 1% isn't gonna make a difference, plus it could just be the program might only go to 99%

R u having a game issues or something?

The 99% issue doesn't matter to me, but I am curious.

However, lately in war thunder and sometimes in Portal 2 I noticed stuttering or lag. Seems to be an issue with the frame buffer or something.

With how optimus works, I wonder if it could be an issue when the optimus copy engine transfers the frame to the igpus frame buffer.

Shouldn't matter, nor play any sort of role in the manner in which u think it does; as long as you go into NVIDIA Control Panel > Mange 3D Settings; set the NVIDIA GPU as the preferred default; set the NVIDIA Power Management to Prefer Max Performance; and set Windows Power Profile to High Performance; the system should never use the iGP; nor keep changing CPU clock speeds up/down.

Overall, 540M just isn't all that great, so don't expect to run most games on High Quality Visual Settings.

The 99% reading is NORMAL. It has nothing to do with Optimus at all. It reads the same. Optimus does only one thing. Either select the CPU GPU or the dedicated GPU. That is it. It's a power saving feature. The math I could explain but for this isn't important for this discussion. Bad-Motha pretty much spells the video card settings that are important. 540M is below on good gaming. On laptops it starts at usually the GTX cards x60+ or a good GT x50 if new or overclocked.

To get rid of your problem honestly is knowing what your laptop can do and how to hand tune each game. That alone is an entire another discussion. I hand tune both my laptop and PC cause I know it's limits and my gaming experience is always good. My laptop has a GT 650 but it's highly tuned and way overclocked but does well but also has a good i7 4-core which is important. But I also know it can only do 1360x768 and not 1920x1080. That knowledge alone saves everything. It can do 1080p on some, but not all depending on how demanding the game is. Some are "fat and heavy" some are "fast and thin" so to speak. Learn what each video setting does and how it impacts your system. When you have that you don't get lag and the fps is good and the game play is good.

I've done that before, though in the game I set it to constent performance, ill change it to max performance in the control panel.

Thx everybody for the comments. And yes, I don't expect my gpu to do anything but play the latest titles at low settings 720P, but I'm happy with that.

However, portal 2 is the only exception, I play that at 60fps 1080P mediumish settings and it runs fine. It's just weird how it does stutter when doing that.

Oh duuu.... I just reaized something that might be causing the stuttering, is it because I only have 1GB of vram? From what I researched, you almost NEED 2GB of vram to play at 1080P smoothly. I play at 1080P.

Yeah, I've been learning about what performes best on my gpu. Even did a little gpu overclocking (don't worry, I have a 200mm laptop fan pushing air into my laptop) and the fps actually went up around 7 to almost 10 fps. But I backed it down to stock, since I can't afford breaking my only good computer.
