Alright. I've been playing PA since alpha and nothing has killed my computer more easily than this nasty bug that is preventing me from playing completely. Interesting thing is, my game has functioned totally fine, even on this build, on this computer, until now. Specs: Windows 8.1. Lenovo Yoga 1 Laptop. dxdiag: http://pastebin.com/UQB6sRBQ As you can see there's a whole lot of CoherantUI_Host.exe crash logs at the bottom... Here's the issue. When I start the game, I connect to a game (or try to reconnect to a game that I already crashed in). The game displays the splash screen, then "Generating planets". It proceeds to freeze, then crash to windows with the following error message box: "The exception breakpoint A breakpoint has been reached 0x80000003 occurred in the application at location 0x01c86f4d" This is a Coherant UI error, which is stuck on top of a PA.exe error. I would tell you the PA.exe error message as well, but unfortunately windows at this point is in a state of panic. There is a big black box that covers the screen that no amount of alt-tabbing, ctrl-alt-deleting, etc. can fix. I have to hard-reboot every time. An interesting thing to look at was the task manager. Although I couldn't see all of it, what I did notice by scrolling through the visible processes is that there were about 20-40 instances of CoherentUI running simulatenousely in the background simultaneously. I don't suppose this is supposed to happen (if it is then that's some scary **** Uber's doing in the background). Some other information: I run PA from steam. I have also tried running the steam shortcut in administrator mode, going to the steamapps folder and running PA.exe directly in administrator mode, running PA in windowed mode (it automatically switches PA back to fullscreen after I click "login" for some reason), and lowering all of my settings to the absolute minimum (even resolution at 50% scaling), and the latter three all at the same time. All of them result in the same crash. All of them break my instance of windows to the point that I cannot even open the metro view. I have also checked my display drivers -- they are updated to the latest version according to my computer. Is this a problem that has a solution, or is it finally the point where PA is too advanced to run on this computer? Keep in mind, I've played PA on this computer in the past, even on this very build, and have had no problems with crashes. The game ran at a solid 15-30 fps on low graphics settings, on the latest build.
Hello, Is your laptop overheating? This may be what triggered the hard crashes. Also, your display drivers are a year out of date: Code: Card name: Intel(R) HD Graphics Family Display Memory: 1792 MB Dedicated Memory: 0 MB Shared Memory: 1792 MB Driver Version: 10.18.10.3282 Driver Date/Size: 8/30/2013 16:05:28, 12078592 bytes It's peculiar that PA even runs on an integrated card with no VRAM at all. Additionally, Code: Memory: 4096MB RAM Available OS Memory: 4006MB RAM The game may be hitting the RAM limit and using a page file, which may have triggered the bolded error message.
Huh. So basically, me running a game like PA on such a laptop is basically a fluke? Hm. It IS peculiar that the game even ran on the computer, yet it has succeeded in this task since mid-beta. I just tested it with a GPU fan program, and it doesn't seem to overheat. The card is freaking old, but windows insists that there is no update. I suppose Intel HD Graphics drivers were discontinued a while ago? Or perhaps the driver updater doesn't know where to look. More scary though is that I was able to squeeze 20-30 fps at times out of this thing... Though I suppose some of the issues are also with PA not handling memory and cycles well on this card. I can only hope it fixes itself. Unless someone else knows a solution. Edit: Do you think running it on Ubuntu might fix some of the issues? Or would it instead cause even more catastrophic failures....?
I've had a look, the Intel core i5 4200u includes the HD4400 IGP. That is actually pretty up to date and should be fine for PA on low settings. You need to get your graphics drivers direct from Intel: https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3719 Try installing those and see what happens. Also have you ever installed any mods? Sometimes mods can cause problems with PA (in particular crashes) so disabling them may help. PA does create a lot of 'Coherent' threads- that's normal, basically 'Coherent' is essentially a web browser (Uber use it for the UI as it's cross platform between Windows, Mac and Linux). To improve performance they've split the UI up into lots of little blocks treating them as separate 'tabs' in the browser. As a result it spawns 1 Coherent process for each piece of the UI (hence you end up with quite a lot of them). Your memory is a bit low for PA, but 4gb is enough provided you keep to small systems. If you could upgrade the memory in your laptop to 8gb that would be a big improvement- I run PA on my old laptop (first gen i5 with 8gb ram) and it actually runs better than my more powerful desktop that's only got 4gb of ram. PA loves ram!
A low memory problem should result in a different error. "SEH exception code 0x8000003 is a debugger break exception." and "this might be a breakpoint generated by the Windows heap manager when it detects heap corruption." First try to reinstall the Visual C Redistributable (vcredist). If that doesnt fix it, try to install the standalone (non-steam) game.
