1) No, you can't disable it in the BIOS.
2) No, I can't return it. I was mostly playing League of Legends/Starcraft 2 so I didn't notice this was a huge issue with absolutely no workaround until now - 8 months later, when I decided to play an old game, PSOBB. Newer games auto-select the correct video card just fine.
3) I'm over-reacting? It's a $1500 gaming laptop, and it can't even play an old ****ty game at 1080p (or in windowed mode at all) without dropping FPS. I'm forced to play it in 720p, because it's using the ****ty intel card. And I'm going to be stuck with it for at least another 2 years.
1) When I did my initial research no one was having any problems with Optimus on the JM. All the posts (which I read on this forum) were simply "I love my JM." As someone not familiar with gaming laptops at all, Optimus seemed like a great feature - if it worked. Since it was the only machine that was reasonably priced at the time (and it was on sale), I went for it.
2) I have not found a single workaround that works with the JM. Most of the threads complaining about optimus on other machines either: a) Go unanswered/have no solution (like my thread on THIS forum), or b) Have a model-specific workaround (eg: a BIOS that actually lets you disable the intel card). You honestly think I haven't spent HOURS googling this before coming here? If it's so easy to fix, then tell me how to do it!
Replying on this thread so other threads are not derailed from your issues.
No I didn't imaging you spent hours looking into this as a google search and three tabs later I've found these links:
This appears to be the defacto way to get manual control of Optimus, however you don't even mention it.
Typing nVidia Optimus in google it auto suggest "not switching" I'm sorry you got surprised here, next time you may want to do your homework a bit better.
If you want a cookie cutter it always works experience for gaming there is always consoles, unfortunately PCs still require a bit of effort on your end to get things working just as you want.
Unfortunately I can't assist further as I can't replicate the issue myself having a JY and have never owned a device with Optimus. I suggest your redouble your effort and focus on Optimus in general and not just Asus laptops.
Perhaps try opening a support ticket with Asus, undoubtedly they get many of such tickets and are likely to have a ready solution... seams like there are many options more beneficial than complaining and bashing things...
