Last drivers and nv app can detect smooth motion and show if it active on nv overlay, also can counter fps after framegen. But i have some serious problem with all transparent textures and particles, hugely tanking perfomance, like a texture caching problem so u need restart vam almost every scene. Also no depth buffer for SSRTGI. Cant get any workaround, not so popular feature. Getting 100fps+ with some sort of additional AA pretty pleasant on heavy CPU scenes
