--- Comment #9 from eliotJ <os...@jadamspam.pl> --- Hi again It sad that it doesn't help... Lately somebody else (nick from krita's IRC channel: 'Stratosfear') has reported exactly the same issue on IRC... He also has AMD CPU. His hardware specs: System Manufacturer: Gigabyte Technology Co., Ltd. System Model: GA-MA785GT-UD3H BIOS: Award Modular BIOS v6.00PG Processor: AMD Phenom(tm) II X4 945 Processor (4 CPUs), ~3.0GHz Memory: 8192MB RAM Card name: NVIDIA GeForce GT 220 For he my solution has resolved this bug :). I also have Nvidia card (GeForce G 103M) and Intel CPU. I have some similar slow down and for me turned off "Use texture buffer" also helps a lot... It looks like this turn off gives boost for Nvidia only. -- You are receiving this mail because: You are watching all bug changes.
