Performance Lag for higher resolution

Aug 10, 2013 7:11 PM

I have developed a touch based flash application with a resolution of 5120x1440.


There is performance lag in two areas.

1) FPS is low (below 33) and Graphic lag is high (sometimes hitting > 80 ms)

2) Touch response is slow (using touchlib)


I'm using a PC of the following specs.

CPU: Intel i7-4770 3.4GHz

RAM: Kingston 8GB

Motherboard: Gigabyte Z87X-OC

GPU: 4x Gigabyte Geforce GT630 2GB

PSU: 1000W


Currently, the GPU Load is hitting at most 20% and the CPU usage is most of time below 50%. If I keep invoking the touch events, the app will ocassionally freeze and GPU Load drops to 0% for a while before coming back to normal and app becomes responsive again.


Is there a hardware compatilbility issue? Is there any way to improve on the touch responsiveness?
