The ToastyX (somehow) makes it possible to enable lightboost permanently without having to select "Enable stereoscopic 3D" in the nvidia control panel. This makes a selection of 100hz, 110hz and 120hz refresh rate resolutions that when used on your desktop or in-game will auto-enable lightboost mode and most importantly, completely bypass the need to have the 3D vision drivers working in the background (which would otherwise still be running even when your hide the stereoscopic with Ctrl+T in-game) causing at least a 10% fps/performance loss. It was my understanding that any refresh rate between 100-120hz would switch on lightboost but turns out you can have non-lightboost at 119hz using the ToastyX and setting a "smaller Vertical Total such as 1125 instead of 1149" as described by mdrejhon (don't ask me why that works lol). The reason for adding this non-lightboost 119hz option is so that lightboost will auto-disabled when i leave a game and return to the desktop. Alternatively without ToastyX i could have chosen the next non-lightboost refresh rate for my desktop use, but that would be 60hz. The difference between 60 and 120 can even be noticed in desktop use.
