Topic: Win7 performance - FF800
After trying hard to make my system running with win 7 and FF800 it seems I somehow succeeded.
Driver 3.014 behaves much better on my machine as previous version. I got no BSOD's using Ricoh 1394 OHCI Compliant Host Controller. In a half hour hard running time (45% cpu load from my DSP app) there was even no errors in Fireface settings dialog.
This "remarkable" performance was achieved by obeying some basic "rules" from Timur on this forum. ACPI-Compliant Battery is disabled, power scheme is set to max. performance, etc.
I use HP EliteBook 8730w with win 7 ultimate 32 bit. By turning off device by device and looking DPC Latency Checker, it is clear, there are performance issues with Nvidia graphics and wireless networking device.
This "remarkable" flawless performance is of course achieved by disabling wireless device and using standard VGA graphics driver. I do not care much about graphics; I use win32 GDI system for "fast" drawings and GDI+ where graphics performance is not critical - no graphics accelerators as DirectX. But I do need wireless networking with my DSP tasks. Timur adviced Broadcom wireless drivers for win7. HP provides Intel and Broadcom drivers, but I can not force Broadcom driver instead of Intel. How can I do that? Uninstalling Intel driver and installing Broadcom allways results with Intel driver. Even delete driver check box doesn't help. Intel driver was unintentionaly installed by microsoft update...
Timur also adviced some software used for tuning performance with nVidia. This post was deleted as forum had problems at that time... Any input from Timur or anyone else will be appreciated.
