Only DX 9 works properly (MSI gaming laptop)

Make sure that Nvidia optimus is DISABLED since odds are that Nvidia's control panel is not properly recognizing PPSSPP as something the dedicated graphics card should be used on and is switching over to the integrated HD 4600 (GT2 variant) which would explain everything.

Optimus has a habit of not recognizing emultor workloads as graphically demanding and since NVIDIA does not care one bit about emulators (to be fair neither does AMD or Intel) the only solution I have found is messing with settings to override the default settings.

How to do this will vary slightly depending on your specific OS.
