Micro Stutter and Low VRAM usage

[leafamouse 0]

Rig:

Mainboard = Clevo P170EM

CPU  =====  I7-3610QM

GPU  ===== GTX-680M 4GB VRAM

RAM  ===== 16GB

HD     ===== Raid 0  2 x Intel 520 SSD

 

========================================

Monitoring VRAM usage via GPU-Z yields @ 300-400 MB.

 

Micro stutter every 3 seconds noticeable when running, driving, or flying. 

 

Setting of MaxFramesAhead never has any effect on detectedFramesAhead. Tried many combinations to force it. (Driver control panel: "Manual" and "Use application settings", .cfg file, and nvidiainspector.)

Even at default  it is maxframesahead=1000

                                detectedframesahead=0

 

vram detected in .cfg is 2 Gig

localvram detected in .cfg is 1 Gig????        (have tried maxmem switch.  no effect)

 

Verified no CPU throttling or GPU throttling.  (Throttlestop and GPU-Z logging).  Happens with all video settings off and 640x480.  Also occurs when using the Intel Processor embedded GPU.  I have killed all extraneous processes.  Used Process Lasso to force priority.  Reinstalled Windows and base drivers.  Installed Dayz and stutter still present.

 

 

For the love of god does anyone else with Optimus have these issues?  It seems to not be recognizing system resources correctly at runtime.

What do you have your video memory set to in game? Anything other than auto (Default in ArmA 2) will cap it at the set level. Make sure you have either auto of default set instead of the others.

It is a known issue. Have you tried disabling your clouds alltogether?

I have tried every Video Memory setting.  There are slight changes in used VRAM, but all exhibit the same stutter.  Default seems to use the highest.

 

=============================

 

I should have been more specific.  I am having this issue with Arma 2 Days.  Is there a way to turn off clouds in Arma 2?

Is that some sort of OEM laptop?

Clevo makes the laptops that you see at Sager and the other "custom" laptop resellers..   It is the same thing as a Sager NP9170.

ArmA likes to stream textures from your HDD, so yours could have a small cache which could be hurting you.

As you have 16GB of RAM, you could set up a RAMDisk and run the game from that.

Unfortunately, the ArmA game engine doesn't like laptops, i7 CPUs and mobile GPUs.

Small Cache on my Hard Drive?  I am running SSDs in raid 0.  

Tried RAMdisk with the, still stutter.

I must agree that Arma doesn't seem to "like" laptops in my case, but if I was willing to accept that, I would have uninstalled it long ago and not made this post ;D

 

All other games seem to have no issues "dealing" with my laptop.  Arma III even runs great.  I am not complaining about the FPS, that is fine.  It is the Micro stutters that I am pretty sure is related to texture loading as it isn't filling up my VRAM.

 

Please keep suggestion coming though.  I know someone out there has had this problem and hopefully defeated it!
