I recommend you do NOT check Particles Shadows. You can add Reflections, Penumbra Shadows and those candy effects over Recommended Settings using checkboxes.
Mod has been tweaked for use those settings.
Please, I know you maybe have a super highend computer, but take a look to Recommended Settings in Config Tool. When installer finish, run Config Tool (shortcut in your desktop). Select your Crysis2 game root folder if installer can't find the path. Download, unrar, and execute MaLDoHD_C2_Setup to run installer. Disable HiRes Textures if you want save some memory or leave them turned on if you have a good amount of memory. Select your resolution, you can use downsampling for better results. Select DX9 or DX11 (I recommend DX11 for this mod, all changes have been made to shine in DX11).
Before use this BETA, I recommend run Crysis 2, select standard Extreme graphics settings.
