There are two games about World War II that are giving a lot to talk about in the Linux world, and those two titles have been created by M2H and Blackmill Games studios. The first one is called Tannenberg and the second Verdun, both already have an update on the Steam store. Can you see the one that brings us M2H for Tannenberg in this link and that of Blackmill Games for Verdun in this other, both with improvements to increase performance with the Unity graphics engine.
Regarding the update of Unity, both titles now run the Unity 2017.3.1p1 engine, a more modern version than the previous version, as the developers have been working on this update to deliver a new performance boost for both titles, which is estimated to be in around a 10 or 25% better depending on the hardware and the configuration of the game that we have selected. A major improvement without a doubt ...
Certainly Tannenberg needs good hardware to work due to its graphical quality, and certainly the performance is not the best, so any improvement is appreciated. In addition, depending on one map or another, the performance may vary, since we can find maps that work well at 100FPS and other larger maps that do not go beyond 40-50FPS to be fluid, so it is somewhat undesirable for most existing gamers. By the way, they have also improved their AI with this update, not everything is performance and graphics.
Tannenberg also seems to have some other strange problems that I suppose will improve in future updates, however they are not serious problems that do not allow us to play much less, but small problems that can alter the behavior of the character we handle. On as for Verdun, it does seem that it works more fluidly and without these small bugs, although in certain distros we may also run into problems. With this I do not want to discourage people from buying it, they are small details that will be solved, but I do like to warn.
