GTX 1080 Ti Global Illumination Performance

On this page we are now going to look at some of the performance of Global Illumination on the MSI GeForce GTX 1080 Ti LIGHTNING Z video card.  We are going to compare “Off” and “Low” Global Illumination options.

What we are looking at in this first graph is the MSI GeForce GTX 1080 Ti LIGHTNING Z video card at the 4:3 aspect resolution of 1024×768 with “Low” Global Illumination. What we are showing is that with “Low” GI the game is somewhat close to being playable in the three demo runs.  The reason why this is important is because at the default “Medium” GI we determined the game was playable at 800×600.  However, by lowering to “Low” GI the game is mostly playable at 1024×768 but there will be more than a few rough spots.

In this second graph we have now disabled Global Illumination altogether.  However, even with GI disabled you can see that 1080p is still not playable.  Therefore, whatever way you slice it 1080p chokes the GTX 1080 Ti with these raytraced features.

However, with Global Illumination disabled moving down to 720p 1280×720 resolution we did find the game to be playable.  So, while 1080p is out of the question, 720p isn’t as long as GI is disabled.

Therefore, with GI disabled 720p is playable (the highest resolution playable on the GTX 1080 Ti in this game) and with “Low” GI then 1024×768 is mostly playable, and finally with “Medium” GI then 800×600 is playable.
