Here are a few tips to avoid unexpected bad performance: Always try to use the latest drivers available for your graphic card. For AMD users that use oldest card, use the newest Crimson beta driver instead of the old official 2015 driver. Using Full Screen mode will give more priority to eternal crusade executable. Therefore, other background process has less chance to disturb the game. Be warn that using borderless mode will use your desktop native resolution! So if you have a native resolution of 1920/1200 you are pushing even more on your GPU. Therefore, resolution changes have just no effect in that mode. We will fix this soon and get resolution box grayed out, showing the actual resolution used by your screen. Do some research about "core unparking" on the web, that can be helpful particularly for some AMD CPU users. Some users are wondering why the game still suffers drop of performance when they are using a GTX1080, it simply because the graphic card rolls his thumbs while another thing eats performances! You can have a set of 1080 in SLI and be bottlenecked by your CPU. When you have a GPU that is over the performance of a GTX 780TI, you'll be most likely limited by your CPU. This is especially true when you're looking at a big portion of the maps with lots of players (like in front of the Fortress Harkus). That said, lots of major drop of performance are CPU, especially when they is tons of players in your field of view. The good news is that we still have good ways to increase performance in that domain! We're working actively on it! Network and overloaded servers may harm performance as well. We are working on it and we are pretty confident to consistently increase the server load balancing and throughput of our networking structure. Soon, we will add more options in the video settings. You will be able to balance your performance in a more picky way. For instance, we are using two different type of shadows. You will be able to override and drive quality for the environment shadows and movable shadows, whatever the quality preset in use (Low, Medium, High, Ultra). Actually, if you use Low quality preset, all shadow are turned off. That's about it for today!
