Slow AVS ?!

[blazer1504]

Yestarday I tested WA 3 at the 1st time , and it feeled like AVS was little slower than with WA 2.78c. So I tested the same preset at the same screen size & display configuration and the preset was over 3 fps slower with WA 3 than with WA 2! !! I got 10 fps with 2.78c and 7fps with WA 3 !!! Why is that ?? Is it because WA 3, or is the problem in AVS 2.5.1, if it's in AVS can the AVS 2.5.1 replaced with AVS 2.5 alpha 3 ??
