If you've been following Tavern Tycoon since its initial release, you would have noticed that Tavern Tycoon has gone through many graphical upgrades,
for example the camera perspective change. (bottom image is the older one)
Then came the post processing effects, giving the game a more well rounded visual. A definite improvement.
Now, we are trying something better - Dynamic Global Illumination.
For those of you who are not familiar with this rendering technique, think of it as a visual steroid (no, really). Basically, it renders light bouncing of all objects in the scene simulating how lights work in real life. Few modern AAA titles feature Global Illumination, which often sets the graphics level up a notch from other titles.
It is also fully dynamic, so I've been playing around with room lights turning on and off, more emissive objects moving around and illuminated FX. I have to tell you that the game's visuals have improved drastically!
The downside to this marvelous technique is that it is relatively performance hungry (I was able to maintain 60FPS on a GTX1070 @ 1080p) so this may not be an option that you can turn on if your graphics card is not good.
Obviously, I will try my best to keep it optimized, but chances of Intel onboard graphics pulling this off is absolutely zero :D But, don't worry, you will always be able to turn it off/on.
Global illumination will ship with the Dev Build DB007 (ETA Jan 31) and will later be pushed down to the main build via Version 0.4.
