I used opensource driver on 4770 and turning compiz off resulted in 20% performance increase
Any time I play Doom 3 with Nvidia proprietary drivers with compiz on the performance falls on my laptop.
Yeah, AMD does not support open driver too. Don?t get me wrong, they released documentation and have at least 3 people working on drivers full day, yet official driver is closed source catalyst.
Yes. Pretty much correct. But small details:
- nvidia does not hinder noveau, amd controls(less or more, bad or good) radeon
- noveau is firmware-free as it can generate the firmware itself, unlike radeon(xf86-video-ati and corresponding kernel driver)
- noveau, in features and performance is same to nvidia, as radeon to fglrx. Well, due to AMD not turning away, radeon is 150% of noveau, yet not even close to nvidia blob or fglrx. In terms of power management noveau is better..
- noveau is clean-room reverse engineered driver, but radeon is not link
- amd is completely satisfied with how, and how fast radeon driver is developed and financed; and how it lives together with fglrx. Well, I?m not. But everyone is free to choose,no?
- if you buy discrete card for 3d, neither of the drivers is usable, both opensource are interesting mostly for legacy unsupported cards(much less impacts nvidia)
