View Full Version : Doc_L: FPS Lag

I think it may just be the optimization for some cards. I have had this problem since Alpha. I posted it on Reddit and didn't get an answer. It just bothers me that my laptop can play Battlefield 4 with over 40fps and this game just kills it. Typical polygon-based games are a bit different under the hood from voxel games where you can fully destroy terrain, and this means that there are some significant optimizations you can do to make Battlefield 4 render quickly that isn't compatible with a voxel game. For example, in BF4, you can precompute lighting, mesh simplification, etc. and bake the information into the mesh so that it'll render really fast if you turn the settings down. (if you want to read the super-mathy details, a good starting point is here: http://www1.cs.columbia.edu/~cs4162/html05s/garland97.pdf ) However, those same techniques don't work well with voxels and cause some really nasty looking visual artifacts, so we're limited to using some very specific techniques. What this all means is, is that a voxel world might intuitively seem to be easy for a computer to draw, but in many ways are more *difficult* - they typically require you to send a huge amount of vertices to the graphics card. Now, this isn't to say that Trove can't be optimized further, or that there aren't possibly bugs causing some slowdown for some people. It's just that comparing performance of a voxel game to a fully optimized polygonal AAA title isn't always a fair comparison.
