[FarCry 3 Bug]Report or not report it ?

[Berillions]

Hi,

I don't know if i must to report this bug or not because it exist on Windows.
It's a graphic bug when you play at FC3 in Directx9 mode, there is no crosshair when you use sniper or arrow. I explain the difference between Windows / Linux+Wine => In fact, it's a bug about "anti-aliasing" in the graphic driver.

Windows :
If you "override AntiAliasing" in Nvidia-setting/ATI-tools and play with Directx9 = This bug appears in-game
If you "Use Application Settings" in Nvidia-setting/ATI-tools for AA and play with Directx9 = This bug does not appears in-game. (I tried with my Win7+Dx9, i never modify Nvidia-settings and always use "AA by Application". Result = I have crosshair for Sniper/Arrow)

Linux+Wine
In the both case ("override AntiAliasing" OR "Use Application Settings") in Nvidia-setting/ATI-tools, there is the problem with arrow/sniper's crooshair.

So i ask this question Vitamin/Dimesio or Dan (and others) : Must i to create a bug report ?
Because it's a Nvidia /ATI settings problem on Windows and probably an bug with AA on Wine, no ?

Thanks
