To fix the issue for AMD, I found that using RadeonPRO BETA 1.1.1.0:

With SMAASweetFX Injector:

Fixes the issues for me. Use RadeonPRO to control the graphics settings and SMAA SweetFX. Do not force Vsync with the program. For me that caused Vsync to not work in Crysis 3. And do not use RadeonPro's overdrive. In Crysis 3 it causes problems. Just stick to the CCC Overdrive.

Also, there is a configurator that was made by one of cryteks R&D engineering people. It is awesome. Works like a charm. If you have two GPU's (SLI/CrossfireX), in the configurator's Miscellaneous menus, 'Force" MultiGPU support.

In using these programs, I have made the game look absolutely beautiful and all the while keeping a steady 60 fps. Runs very smooth, for having everything cranked way above the in game 'Very High' setting. Hope this works.

Now, for nVidia users, try to find a RadeonPRO equivalent. The SMAA SweetFX Injector will work with both GPU's (AMD/nVidia) and the configurator. Good luck guys.

Could you possibly record a video to show us what it looks like? I'm a bit hesitant to try it out, seeing as Crytek will probably release another patch in the coming week.

Not sure about the video, not my thing and never looked into recording game footage. Reason being, because when you upload it, whatever service you're using, (i.e. Youtube, etc.) compresses it and you never get the full quality anyway. I could try though. I'll look into it and see what is up, if time permits. Real busy lately.

But in the mean while, I will say this. These little programs I have used for a long time (besides the CRYSIS 3 configurator.), with many different games and never once ran into a problem. These programs implement the tweaks in a very stable manner. You are not changing any game files or system files. It did take me a bit to get over the learning curve with RadeonPRO, but once I got it, it is an essential program for gaming. At least to me. Good luck and hit me up with any specific questions and I'll try to help you out.
