brushes, erasers lag in photoshop cs4 64

[briligg]

I recently installed Photoshop CS4 64 bit, version 11.01. Even using a paintbrush 10 pixels across, the paint line lags a second behind the cursor. Same for similar tools like eraser and smudge.

My machine crashed yesterday and i got a blue screen saying there had been a clock error. (I didn't manage to get a photo before it disappeared.) I had been working in Photoshop, on a file under 4 Mb.

I run windows 7 64 bit, 7100, my bios and all my drivers are up to date. Kaspersky antivirus came with my mb, but never ran properly. I downloaded an update for windows 7, but still it caused windows to block it, saying there was an incompatible driver (?). I restored the system to before I installed it. That didn't help either.

help???

Welcome

Can you upload the minidump file?

 

[briligg]

okay. how do i do that?

 

[briligg]

There's one .dmp file on my system, it was made at the right time to be for that blue screen. It's 311 MB. Hm.

 

[briligg]

wait, that was memory.dmp, i guess it's a system file... the minidump folder is empty... but i most definitely got that blue screen...

 

[briligg]

alright, if nobody has any thoughts, i'm going to go ahead and reinstall windows

Make sure your settings are similar...

Well, windows is reinstalled, and everything is updated again (the bios update should still be there, right?) but i have the same problem. just tested it with a 5 pixel brush - it lags half a second or so. maybe that doesn't seem like much, but it makes it hard to draw a precise line.

i just tested brushes in gimp and painter 11. they work fine. i had vista 64 on this machine before and didn't notice any problems with brushes in ps, but i switched os after a week (the machine is new) because it had crashed 4 times, once when nothing was open except a game of solitaire. maybe i just never tried brushes in ps before. 7 has crashed once so far, but it still seems more stable.

anyhow, the problem seems to be between photoshop and the rest of my machine. i guess i'll have to hope a patch comes out, and use painter and gimp for now.

btw, never found anything in the minidump. i opened it in explorer. could the file have been hidden? there doesn't seem to be a minidump folder now. Does windows create it when there is a crash? i guess i let that file get lost. well, maybe i'll be lucky enough to have a similar crash...

Is your monitor refresh rate set to 60hz?

My bad. It is hidden. you need to show all files and folders. You can right click on the folder and see how big it is. each dump should be larger than 30k

you do have a way of challenging my skills, tgs...
i haven't adjusted the monitor, other than to up it's resolution. i can't find any information on what hz it's running at - the monitor's own control panel doesn't have that as a variable, nor does the nvidia control panel. so if 60hz is standard, i imagine that is what it's running at. anyhow, if it was a problem with the hz rate of the monitor, wouldn't that screw up brushes in all programs?

 

[briligg]

the monitor is kind of old - it's a crt. i'm waiting til there is a flat panel that is larger and higher resolution than my good ol' crt before i switch.
