ksp lags on decent pc

[noobsrtoast]

im running with an amd a10 7850 with 3.7 GHz clock speed and 16gb of ram, if i lower the setting i can get it up to 60 fps on unmodded but i shouldnt have to, this thing should have no problem running ksp with at least 60 fps on ultra settings

Please see the "!!! PLEASE READ BEFORE POSTING !!! - Stock Support & Bug Reporting Guide" sticky thread in this sub-forum and follow the advice/instructions it contains...

Yep, me too. KSP is limited to using a max of 3.8 Gb before it crashes. It can only utilise a single processing thread as well, which I believe means you can barely use all of your computer's resources to help the game.

The next update should help with this big problem. The game is updgrading to Unity 5, which allows for multi-thread processing and has 64 bit support. This should mean you can use all of those 16gb of RAM to run KSP.

My advice would be to wait until the update and then see what happens. That's what I'm doing 

Happy Flying

because I don't know what kind of preformance changes to expect from a practical point of view

The trouble is that Squad aren't certain of this either yet.  They are still making optimisations and bug fixes to the code, it could get faster than the version currently in QA before release or, if they have to remove one or more optimisations or write some complex code to fix a bug, it could get slower.  They have indicated there are performance improvements but, sensibly, are not putting any figures on it as it could very well vary considerably between different machine setups or with different vessels (well, entire game state) or as further changes are made before release.  What do you think the reaction would be if they announced a 25% increase in performance and a substantial number of users (or even everyone) didn't get that...?

KSP isn't your average game. It's very poorly multithreaded*, CPU-heavy, and GPU-light. CPU load goes up the more parts you have on your vehicle. That means your CPU's single-threaded performance is king, and that means that a modern fast-clocked Intel processor will run KSP much better than anything AMD offer.

(* Contrary to widespread belief, KSP is multithreaded, it's just that 90% of the work is on one thread.)

And to be honest the a10-7850 is a firmly budget processor. It's not awful, but you shouldn't be at all surprised when it has troubles running some games even if you have a good graphics card. And if you're relying on the integrated graphics, well you're pretty much on the bottom rung of the gaming hardware ladder.

Try Lowering settings, or install a game booster. (I have Razer Cortex)
