It seems that nVidia users seem to draw the short straw with Lightroom. When Version 1 was released, it took a while to find out that certain performance issues were due to the use of nView. Now with Version 2 it seems there are different performance issues with nVidia.
However Flickr user MarkW Photo has found settings that greatly aid in the speed of the brush tool for Lightroom 2 nVidia users.
“I have finally fixed my slow performance issues with LR2! Today I did a bit of playing around with different performance settings. I’m using LR2 on a HP Pavillion 6258se Laptop. It has an 80GB Hard Drive, 2GB of Ram and the processor is a 1.8 GHz AMD Turion ™ 64 X2 Dual-Core. I had Windows Vista installed months ago but I downgraded back to XP due to Vista issues. First I opened the windows task manager so I could monitor the performance of Windows while using LR2. I noticed when using the develop tasks the performance stayed around 50%. When I used the retouch brush tools the performance still stayed around 50% but the brush tools were still slow. The more I brushed on the image the slower the brush refresh became. This told me that there must be a video performance issue and not necessarily a processor problem.
