I plan to buy a new laptop sometime and I have been doing a lot of research trying to find the best one. Unfortunately a lot laptops include Optimus and it has very little Linux support. I have a laptop in mind that seems nice to me, but unfortunately it has Optimus. I am stuck in an unfortunate spot. I could spend more money on a laptop with a more expensive GTX670 or GTX675 graphics card, and because these cards do not appear to have Optimus I might have a better time using them with Ubuntu in the first place as well as not have to take a performance hit. The thing is, I do not particularly need such a high end graphics card. A GTX650M or GTX660M will suit my needs, if it gets a frame rate comparable to what it would on Windows, or a slight penalty. I also prefer the laptops with these weaker cards because they tend to be a pound or two lighter and they have vents on the side instead of the side and back or only back.
So that is the back story. My question is, how many FPS hit can I expect to take as compared to Windows 7 performance if I use Bumblebee to get Optimus support? Also, how many FPS hit can I expect to take from Wine? I have used Wine before but never in a situation where I am cutting it so close on the FPS I need versus the FPS I expect to get with the graphics card I want. Even if I use a GTX650 on Windows I will be cutting it close, with only a few FPS to spare while being able to maintain the graphics settings I would prefer. So if the hit is only a few FPS it will be fine, and if it is a few more a GTX660m will probably be okay. But if it is a huge difference, I might be forced to shell out more bucks for a laptop that I like less just to be able to avoid Optimus !! Some feature.
One more thing. Will Bumblebee work on any Optimus laptop, even if it is Ivy Bridge? I would hate to spend over a thousand dollars on a laptop and find that I can not use Ubuntu with it.
