Some of these systems are not experiencing the framerates they would like to see. We see quite a few people with systems that we can only described as "high end". High end machines (e.g: Hexacore CPUs with NVidia 680 or above) In addition we suggest to turn of shadows for the time being on such systems. Either run the game with NO AA, and shaders set to LOW or set the resolution to 720p. On these systems it is strongly suggested to reduce those settings that affect the fillrate. I am seeing a lot of people with such mid range graphic cards running the game in very high resolutions and high graphic settings. Mid range graphic cards (this includes high end models with an "M" for mobility at the end.): If you have an nvidia card, to force the nvidia card : The game uses my integrated intel graphic card and not my nvidia card. It may have zero effect on the framerate in a normal zone but great effect in an asteroid field. The LOD and viewdistance are greatly dependent on the situation in the game. Do not get fooled by the fact that turning LOD and view distances to low may not have an effect immediately when you try it out. Settings like the LOD level, the view distance and enabling the shadows on the other hand also greatly affect the CPU load. If you have a very fast graphic card (see section below for top range models), then some of the graphic settings (shader quality and resolution) are not very relevant for you, because your system will always only be as fast as the CPU allows it to be. With X Rebirth this is only true in about half the situations.Ĭhanging your graphic settings can have an effect on both the CPU as well as the GPU. Almost all mass market mainstream titles nowadays are render bound (by the GPU). One thing that you will find is different with X Rebirth compared to most mainstream graphic intensive games (read shooters) nowadays, is that X Rebirth has very high requirements for your CPU. What is causing the low framerate: CPU or GPU We ARE working on other performance improvements, but it is important to understand that with any "above midrange" system you are far more likely to be memory or CPU bound than that you are GPU bound (this also means in these cases graphics settings have no effect). This is only one of many possible causes obviously. If the performance of the game suddenly drops it may be because your machine is swapping memory. Since we have a lot of background AI and pathing tasks crunching heavily on memory intensive operations, sometimes this can conflict with the memory intensive graphics calculations. Unfortunately X Rebirth behaves very different from a first person shooter in terms of performance. While this is above our minimum system requirements, it is a combination that does not work well. Machines with very powerful GPUs (680 / 780 etc), but with only 6GB of ram for example. Looking through DXDiags in the last few days we have seen a number of oddly balanced machines. *UPDATE* - Available memory can affect performance This being said however there are also a lot of misunderstandings on what framerate is achievable with which system and graphics settings combination. First of all the most important thing: Some of these definitely show bugs in our engine when running on specific hardware and we are working on fixing this as fast as possible. I have looked through more than 150 DXDiags already and I would like to post a few conclusions. We are very sorry to hear that a fairly large number of people are experiencing bad performance when running X Rebirth.
