I have photoshop CS4 running with NVIDIA graphics cards on both my desktop PC and Laptop running Windows XP Pro 32 bit. When I use any of the brush, erase, etc tools as the brush enlarges it slowly starts to disappear. When the tool is very large it totally disappears. I was given a suggestion earlier in this forum to update the NVIDIA drivers which I did and this fixed the problem until I had to uninstall photoshop and reinstall it. Now I have the problem back again and can’t seem to fix it. I tried reinstalling the drivers but this did not help. Any suggestions on how to fix the problem one more time would be greatly appreciated.

With regard to my laptop I am using a newish Hewlett Packard Mobile Workstation model Compaq 5810w. I have tried to update the drivers for the NVIDIA Quadro FX 570M card but the NVIDIA websites says that for laptops the drivers are supplied by the manufactuer of the laptop – I have tried HP but with no luck – again any advice would be appreciated.

I am using my laptop at the moment (travelling) and it starts to disappear between 70 and 80 px(?) brush size.

Just downloaded the most recent NVIDIA driver for the laptop from the HP site that I could find dated 28-10-2008 (previous version was mar-2008) with no joy.

I did actually fix the problem on my desktop PC by updating the NVIDIA driver but had to uninstall Photoshop CS4 (for unrelated problem) and reinstall and when I open Photoshop CS4 the brush problem has reappeared – tried re-installing the NVIDIA driver but it did not help. Was wondering whether I should un-installed the driver first then re-installed it.

Interestingly I have also noticed I have the same problem with the brush tool in Lightroom 2.1 on the laptop.

My laptop is a HP mobile workstion model Compaq 8510w.

Thanks
