Direct3D9 crash?!

[rainbowfarts]

Hi everyone,

I'm new to the forums, but I've been a long time user of Dolphin. I just updated to the latest Dolphin after a 6-month dry spell (summer has arrived, at last =]). But something I realized is that when I run it with my GPU (GeForce GT 630M w/ Optimus), things go a little awry. I go to set the graphics backend to Direct3D9, and Dolphin immediately crashes. Then every time after that, Dolphin ends up crashing whenever I try to access the graphics settings. I even tried using the old build I had, 3.0-798, and the 3.5 stable release and the same thing happens.
All is not lost, I can access the graphics settings again if I delete the Config folder from the Users folder. But my goal is to play Twilight Princess, and I experience huge amounts of lag with Direct3D11 or openGL. Note that I don't crash when I use D3D11 or openGL. I'm seriously at a loss with this, and any help would be greatly appreciated. Thanks.

Give us your system specs.

also have you tried starting from scratch and downloading 3,5 and opening it that way? (deleting anything you had thus far (outside of your mem card)

Leave the HD 3000/4000 selected in Dolphin and force Dolphin to a high-performance profile in the driver settings.

Hi guys,

I tried a clean reload, still the same (made sure to grab my memory card file on the way out, though).

I tried setting Dolphin to a high performance profile in the driver, while loading it with the HD 3000 selected. It runs, but it's still running off the HD 3000, and not the GT 630M. I even monitored it with GPU-Z. I've noticed that Dolphin only recognizes one GPU at a time...

That aside, when I set things up in the NVIDIA control panel, it sets the "default graphics card" for the program. I've been able to pull it off flawlessly with other programs and other emulators (and even Dolphin, once upon a time). What happens is that it will load the program using that graphics card, and that one only, so if Dolphin reports that it sees the HD 3000, that is what it's using. I'm down for tricking my programs, though, so if there are any other strategies...

Anyways, here are the specs of my computer:

Lenovo IdeaPad Z570 (has a physical switch which can actually turn off the high performance GPU built into it)
Windows 7 64bit
Intel i5-2450M 2.50GHz
6.0 GB RAM
Realtek HD Audio
1 GB GeForce GT 630M (updated drivers)
Intel HD Graphics 3000
