Scroll wheel zooming issues on a fresh install (plus excess cpu usage)
Scroll wheel zooming issues on a fresh install (plus excess cpu usage)
(OP)
I've been having computer issues and have had a warranty motherboard and hdd exchange, followed by a whole new computer (dell laptop.) Originally I had Solidworks installed and everything worked great. After the new motherboard/hard drive, I reinstalled and noticed that sometimes the scroll wheel zooming was hyper sensitive.
I use the scroll wheel to zoom extensively; that's how I move my view point around. Zoom out, then zoom back in elsewhere, with middle mouse button for dragging/rotating the part around.
At first things work fine, then maybe an hour down the road or maybe a day or two with the computer up and running, suddenly slight movements of the scroll wheel will result in excess zooming. The part will become a tiny spot then disappear, and it's difficult to get zoomed back in on it. So I'll save all of my files, close Solidworks, re-open it and it works fine again.
Now with the whole new computer (different model) this scroll/zoom issue is constant. I can't use solidworks like this. Also, with Solidworks open I'm noticing excess CPU usage, like 10-12% with one of the cores' threads pretty much pegged. Closing Solidworks doesn't fix this. I have to use the task manager to manually end the solidworks.exe process before the computer will relax and the fan slow down.
I haven't done anything different with this install than the other one that worked fine. Any ideas? I've tried changing the mouse settings to 1 line per scroll wheel click from 3, and no change.

Does the new laptop have a different OS?

The excessive CPU issue persists, though. ~15% usage even when idling with no files open, and after closing Solidworks, SLDWORKS.exe process must be shut down manually through windows task manager otherwise it'll keep running and laptop fan going full blast.
Old system specs:
CPU: i7-820QM (4 cores, 8 threads, 1.73GHz (3.06GHz max turbo), 8MB cache)
GPU: AMD Radeon HD 6470M (1GB video memory)
RAM: 8GB, 1333MHz
OS: Windows 7 Ultimate
New system specs:
CPU: i7-2820QM (4 cores, 8 threads, 2.3GHz (3.4GHz max turbo), 8MB cache)
GPU: NVIDIA Geforce GT 540M (1GB video memory)
RAM: 8GB, 1333 MHz
OS: Windows 7 Ultimate
On the old system I was able to do a software modification to the GPU driver; basically I changed the stated name of the graphics card to FirePro V7750 (on Solidworks' supported list) to trick Solidworks into enabling all functions, such as RealView, even though it was technically an unsupported card. Before performing the mod, though, everything still worked fine, just with RealView disabled.
Do you think the excess CPU issue could be related to the unsupported graphics card?

Can you change the graphics card back to factory default settings?
Can you test with an approved graphics card?

Are you using the Windows Aero theme?
What A/V are you using? Was it disabled during SW installation?

While there, make sure Dissection is disabled ... unless you use it of course.

I just wanted to know how did you do the graphics card modifictions?
I just bought a notebook wi amd radeon 6470m 512MB dedicated memory and was wondering if i can make that modification to trick solidworks and activate all functions? Thanks in advance to all.

There are other methods of soft-modding both ATI and Nvidia cards, also. Just search for soft-mod and Solidworks...
