开启Aero只能解决桌面卡的问题，一进游戏还是固定在30FPS。而优化程序可以自定义参数，可根据自己的显卡设置
下面这两个参数我将它设为<cmdline>f90 p1</cmdline>，这样运算时玩些小游戏几乎不成问题
kernel frequency: f (default 30)
The application determines the size of the work packages sent to the GPU in a dynamic manner. It
tries to get the number of executed packages per second above the value specified here by
splitting them to smaller ones. The OS is completely blocked from accessing the graphics card for
the duration of one package leading to a somewhat sluggish behaviour of the user interface.
Limiting the size and therefore reducing the execution time per package creates more opportunities
for the OS to slip in between two work packages and to react to user input. The default value of
30 Hz is tuned for usability of the system. Reducing it could increase the throughput of the app
slightly.
Example:
<cmdline>f10</cmdline>
The app will try to run 10 work packages per second (limits the execution time to 100ms or shorter).
Priority: p (default 2)
All BOINC applications normally run with the lowest possible priority to not disturb other
applications. This can lead to a low GPU load, as it may be not possible to fire up the next tasks
if all cores of the CPU are under load. Raising the priority may help here. BOINC recommends a
slightly increased priority for GPU applications. This setting is the default. Possible values:
p0: idle priority, used by CPU BOINC applications
p1: normal priority in idle priority class (below normal), this is recommended for BOINC GPU
applications, but apears to be not enough to enable millisecond polling of the GPU with Vista
p2: normal priority in normal priority class, the default
p3: normal priority in high priority class, use with care!
The priority will affect how much time it takes for the the app to get back control if it releases
its time slice (see also option b).
Example:
<cmdline>p3</cmdline>
This raises the priority to high (not recommended). |
