Hello,
I'm having a video card issue. Hopefully I explain this properly.....(fingers crossed).
I've just purchased a brand new Dell laptop, here's the spec's:

System

Manufacturer Dell Inc.
Model Inspiron 7720

Notes
--------------------------------------------------------------------------------
The gaming graphics score is based on the primary graphics adapter. If this system has linked or multiple graphics adapters, some software applications may see additional performance benefits.

I've got a NVIDIA GT 650M installed and device manager says its working fine with the latest driver. I've configured the NVIDIA control panel to use this video card (650M) when MWO is run. However my problem/confusion comes from when I turn off the integrated video card (in device manager) shown on the pasted in spec's above. Then MWO will not run at all and gives a "unsupported device error". I know for a fact others are using the GT 650M video card with this game from other forum posts. So how is it that I can run the game using both video cards enabled, but not with the better of the two as the only one enabled?

Any advise is appreciated.

Thanks

laptop is your problem

So I tried uninstalling the driver for the intergrated video card, then tried opening MWO. It would not open and still gave the unsupported device error. Then I tried uninstalling MWO and reinstalling it with only the NVIDIA GT650M card enabled, and it still would not open MWO and still gave the error.

Now I'm stumped as the only thing I can figure is there has to be some kind of load sharing, or pass through going on where my system has to use both video cards because it runs like crap with the integrated disabled.

I hate this part but I guess I've got to call Dell support and spend 3 hours arguing with a foreigner over what is actually wrong with my laptop.....hopefully they speak english this time.

Seriously?

usually, pressing the "del" key during boot-up will allow you to access the BIOS. Usually. (DISCLAIMER: I do not play on laptops so my POV is from a desktop perspective.)

Maybe

it can be one or all of the following possible bottlenecks: the fact that it's not really a gaming Laptop, or it's the cpu, video, or RAM

Optimus should have it automatically switching to the dedicated card on launch. . but the 650m is NOT a very powerful card. It may be that the performance just isn't there in the first place.

I know the 5870m and 460m were down to unplayable FPS as of patch before last, and I haven't tried my 570m lately [though that one is several cuts above either the 650m OR the 5870/460m] I may give it a shot in the morning and get back to ya. . because if THAT one is unplayable, there's not much that can be done.
