Doesn’t help mine at all. Exactly the same.
Thank you – for once a practical response.
I entered these settings, closed and re-started. CS4 crashed and burned ("Tell microsoft…") I persisted, and I have to say that the second restart produced a situation in which the brush lag had alomst vanished.
one of this exactly produced confidence in the poroduct. We all seem to be beta testing something, in a deeply inefficient manner.
So including 2 from the other thread, thats 3 "improvements" and 1 "no joy" 🙂
I had disabled Open GL because of horrible brush lag. I’m using a Nivida GeoForce 8400 GS with Vista 64. I tired these setting and no change. Then I realized I had an old video driver. I updated the driver and works great. So I guess the moral is to check video driver and make sure it is up to date. I thought I had, but … anyway – happy camper.
Hi guys,
As I am having very little problems with my system I though I should post my specs and settings for comparison reasons.
System – Asus p5Q deluxe,
Intel quad 9650 3ghz,
16gb pc6400 800Mhz ram,
loads of drives ( system drive on 10K 74gb Raptor, Vista partition on fast 500gb drive, Ps scratch on an another fast 500gb drive, the rest are storage/bk-ups ),
Gainward 8800GTS 640mb GPU,
30ins monitor @2560×1600 and a 24ins 1920×1200,
Wacom tablet.
PS CS4 x64bit
Vista x64
All latest drivers
No Antivirus. Index and superfetch is ON, Defender is ON No internet connection except for updates
Wacom Virtual HID and Wacom Mouse Monitor are disabled
nVidia GPU set to default settings
On this system I am able to produce massive images, the last major size was and the brushes are smooth until they increased to around 700+ pixels then there is a slight lag of around 1 second if I draw fast, if I take it slow then there’s no lag. All UI is snappy.
I have the following settings in Photoshop CS4 Preferences:
Actual Ram: 14710MB
Set to use (87%) :12790MB
Scratch Disk
on a separate fast 500gb – to become a 80gb ssd soon
History state: 50
Cache: 8
OpenGL – ON
Vsync – OFF
3D Interaction Acceleration – OFF
Force Bilinear Interpolation – OFF
Advanced Drawing – ON
Use for Image Display – ON
Color Matching – ON
I hope this helps in some way too…
Hey
Have same problem with Brush lag. Have tried all the above and more.
My system:
Gigabyte P35C-DS3R with latest Bios
Intel Core2 Quad Q6700 2.66 Ghz
8 GB Corsair 6400 RAM
Geforce 8800 GT with latest Nvidia driver
Windows Vista Business 64 bit SP1
Photoshop CS4 64 bit
Photoshop performs OK with some kind of work like picture adjustements etc. but I have big problems getting a descent brush respons time. If I raw a brush stroek it takes a lot of time before anything shows up at the screen.
I have tried changing settings in Open GL in PS – and have tried switching it on and off. No result what so ever. Not even a performance difference between on and off.
I have changed Nvidia driver settings (as some one has stated in other posts) with no luck.
I really need no brush lag because I draw a lot in PS. Please help?
🙁

Not having any problem with brush lag , However… I do have another strange brush problem and was wondering if anyone had experianced this. when i select a brush, the Outline/preview of the brush that acutally shows you the size of the brush, get cut off when i enlarge the brush. It still paints the full brush shape (like will still paint a Full circle) but the preview outline to show you how big and the boundries of the brush is cut off and all i see it the top lefthand corner. Makes it very hard to paint, or erase or do anything with brush as i cant see the boundries of the brush without acutally painting… Any ideas????
Yeah, I saw that as well, only one quadrant of the brush shows.
Went back to CS3 and sent CS4 back. At least until I get a new PC (and PS gets an update).

The problem is in the video driver. At about 64×64 pixels the rendering of the cursor switches from hardware to software. Apparently ATI card drivers perform this switch properly and there are no problems. Some nVidia card/driver combos have this problem but nVidia appears to be slowly fixing the problem for their cards via driver updates. AFAIK the only solution to the incomplete cursor problem in CS4 is to get nVidia to fix their driver for your card.
