I have gotten 504 errors, game crashes while loading light maps, crashes when saving about 30% of the time, but also freezing after the game reboots itself. If I save and reload it, this does not resolve the frozen state. I have to completely exit the program in order to resume work on the level. This is making the task of lighting an urban outdoor scene at night very time consuming.

Admittedly, my scene has about 10 buildings, roads, sidewalks, a few street lights, a few props, and trees, with about 15 light sources set to both static and dynamic.

I have validated the software in Steam, and am running it through Steam.

Any help with this would be very much appreciated. I'd rather not give up on this map. Other, less complex maps have this issue at times, too, but this one being more asset heavy seems very unstable.

My Specs are:
Acer Nitro 5
2.4 GHz Core i5
GeForce GTX1050
32Mb SDRAM

I have a Nitro5 and have none of these issues.

First thing to check, is GG actually using your 1050? On an empty map go into test mode and when its loaded up press F11 it should tell you which card it is using.

If its using the onboard card instead of the 1050, then there's two things to try, firstly close out gg and go to you windows settings, under display (i think) you will find a windows scaling drop down, if this is anything other than 100% then change it to 100 and try gg again.

If that doesn't work then go in your nvidia control panel and make sure to set it to the nvidia card as default, then check gg again.

If neither works then i don't know

Yeah, also when GG goes into reboot mode just kill it via Task Manager. In my experience GG never recovers properly so you will have to restart it anyway.

I have noticed the same thing, but not as much. Locks up when I try to save after light mapping. Once I accept the error (click OK), then it is trying to do the "resuming..." business, but it always comes back with the previously loaded level, without the new additions. Yes OldFlak, you are right, at that point you need to kill it via task manager and restart the PC. Then immediately redo what is that you were doing and then save. I have gotten to the point, when I need to make any changes, or start adding on new stuff, I first restart the PC and then GG. Do my thing, save and restart again. Yes, a PITA, but this way I have a better chance to do a proper save. DLLs in windows stay loaded in memory unless you restart the PC, hence the problem reappearing if you don't.
Cheers!

I did as Belidos said, and it seems to have resolved my issues. After adding the GameGuru .exes to the 1050 the game is running smoother and has not yet crashed after several light map adjustments.

I have had to run task manager just to get out of the runtime, so GreekToMe and OldFlak, I have found that your methods have been more than necessary. Rebooting the computer helped only a bit for me. It really was that my card was not assigned the proper tasks!

Thanks to all for your help. Surely appreciated.

I have to say that I rarely have GG crash - only when I break it with bad lua, but even them most times it will just throw an error that I can say OK to, and it will keep loading as normal.

But I don't light-map as a rule - because it just fluffs something up - and if I do I never save it and re-load it, so maybe it is just the light-map doesn't like your system or something...

The GG can be frustrating at times.....

OldFlak....

You know, the GG developers recommend (I heard this somewhere?) to do all of light mapping as the final step, at the very end of the game development. But I am glad you resolved your problem.
Cheers!

Glad i could help, i have the exact same laptop and had that issue to start with. It's primarily the scaling that is the biggest problem, the Nitro 5 defaults to 125% and although it's 1920x1080 at 125% Gameguru sees it as a different resolution and for some reason uses the on-board intel drivers instead. Even when forcing the default to be the 1050 i found that with 125% scaling on gameguru just refused to use the 1050 and defaulted to the intel.

(p.s good choice on the laptop, it's not exactly top end, but for it's price range and specs it's a very rugged and capable laptop, there's not much you can't do with it)
