Graphics processor selection.

SantaClaws

Early on when I first got NS2, I had a problem with my Intel HD 4000 processor taking over instead of my Geforce processor. This caused big performance issues, but I managed to fix it by setting it up in the nvidia control panel.

Since the last patch, I can't complain about performance, I'm pretty consistently at 120 fps. However, when I launch ns2, the console reads:

Direct3D 9 initialized: Intel(R) HD Graphics 4000

No mention of my Geforce graphics card. So I'm wondering, if NS2 is somehow stuck on using my cpu processor instead of gpu again. If so, is there a way I can fix this? -if not, what am I misunderstanding here?

I have tried setting it in the nvidia control panel and I have also tried

Right+Click>Run with graphics processor

on the desktop icon.

Again, I'm not having severe performance issues, but I'll take any frames I can get.

As a temporary fix, disable your integrated graphics from the bios or from device manager.

NS2 automatically detects and uses your GPU instead of the integrated... but the nvidia ctrl panel setting shouldn't hurt.
The battlefront Nvidia drivers came with all sorts of issues though, and have since been updated I believe. Try updating them or rolling back to test.

Could just be a driver related issue. (for the integrated processor as well!)
Alternatively, could you verify whether your GPU is being used with MSI afterburner while running NS2?

Lastly, be sure your Power Options are set to HIGH!

If you're on a laptop, never disable your integrated GPU, as it's used as a frame buffer for the Dedicated GPU.

Best to add ns2.exe to use ur Nvidia chip only, in your Nvidia control panel.

I am on a laptop, and yes I just discovered that this was a bad idea

I have added the ns2.exe to the nvidia chip only which is why this whole thing is so confusing!

I don't know what this means... No?.. I guess?

Also - both drivers, for the integrated and the geforce cards are up to date. I wouldn't know how far back I'd have to roll it back (

In the nvidia control panel there's an option

Display GPU Activity Icon in Notification Area

Apparently NS2 shows up there.



EDIT: However, it does so even if I change the setting in nvidia control panel to run with the integrated graphics. + I just confirmed, by using integrated graphics I have the same performance.

So it's definitely using the integrated chip instead of the nvidia chip.

IronHorse

if you run msi afterburner in the background while playing ns2 , you can alt tab and then see your GPU processing / being used

@IronHorse It appears that it is using the gpu in ns2.

So what does this mean?

It means that NS2 is actually using your GPU, but just incorrectly reporting the GPU it sees.
I would not worry. This explains why you've seen no performance loss, too.
