General Capability Problem

[Saras]

Hi all,

My very eager approach towards digital painting lately came all of a sudden to an end as i realized that none of all the usual programs work on my PC ( HD4870 512MB, Dual core 3,2, 4 Gig ram, more than 5 giig on C).
I even bought a wacom for 200 bugs...

every single of them (tried Photoshop cs3 and cs4 and Painter) cones with a hughe brush lag which you simply can´t work with ...

My question now is what your PCs have which mine doesn ´t.
Although i can play really every game on full quality i am not able to perform a big-sized brush stroke? this can´t be true! Most of the time the cpu-efficiency jumpes to 100%...

Pls help me and excuse my poor english^^
and sorry if wrong section

It could be a multitude of problems, check your temperatures on your CPU and GPU. You can download speedfan to do this. You can also see if your power supply is working well by buying a PSU tester for $5 at your local computer store. Download memtest to test your ram, run it for 8 hours.

Since there is no way to know if you are infected with a trojan or virus, the best thing to do is to reformat then try photoshop. If it still continues to lag it is most likely a hardware issue.

There's going to be brush lag no matter what. My system is a quadcore 4gb memory with 60% of its resources available to Photoshop. I still get brush lag.

I've found, curiously enough, that hitting tab to show and hide your tool menus tends to alleviate it somewhat. Not sure why.

If you're able to run cpu-intensive programs without a hitch and photoshop is slow, try increasing the available RAM and scratch disk size. Also, defrag your hd's, to get some more speed out of there.

With the big dualbrush or textured tools, it's seeking for that referenced texture file while computing the blendmode and opacity, angle, direction, pressure, etc of the current stroke. Free up the CPU cycles a bit and you shouldn't have as much of an issue.
