The quick-and-dirty way is to increase the maximum time per frame, which lengthens the KSP simulation timestep at the cost of making the simulation slightly less accurate.įor this, all I can suggest is to keep your craft small, avoid any CPU-hungry background processes, keep your laptop cool (prop it up so the bottom fans are unobstructed, etc), avoid some of the more CPU-hungry mods (my best guess is that FAR will be the worst offender), and, well.

You've got to calculate forces on every part by every other part, manage on-rails vessels, manage CommNet, aerodynamics, heating, solar panels, and many other things which hit the CPU for each and every simulation timestep. When it comes to the CPU, this is usually (unless there are memory problems) the limiting factor for KSP, which is a very physics-heavy simulation game that puts huge loads on the CPU. Even with the relatively wimpy integrated GPU on that laptop, I doubt it's the issue. The general advice is to set graphics settings down until either your FPS plateaus (GPU is crunching frames faster than the CPU can push them to the GPU), your FPS exceeds the refresh rate of your monitor (usually 60 FPS), or you're just generally happy with it.įor KSP, fortunately, graphics are rarely limiting, particularly when notched down to minimum. The speed usually doesn't matter too much generally, standard DDR3-1600 or DDR4-2133 is more than sufficient for the task.įor the GPU: This is usually the limiting factor for AAA games, since those games tend to be computationally simple, but packed with very demanding graphics elements. 4 GB can be kind of tight, 8 GB is usually enough unless you're one of those 'Mod It Till It Crashes' types, and 16 GB would be overkill. Second, there are three main elements KSP hits: CPU, GPU, and memory, of which the first is limiting for high-end computers.įor memory: you need enough of it to load KSP, any mods involved (particularly parts mods with memory-hungry textures and models), hold any background processes, without putting anything important into swap memory (basically using the hard drive/SSD as extra memory as a last-ditch effort). The HP website boasts 'industry leading processor so you never need to worry if it's powerful enough' that is a colossal joke. First, I am very, very unsurprised to see that dinky little laptop running KSP poorly.
