Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

CPU Overheating when building light

As the title says, my CPU temperatures are breaking 100*C (at about 85% capacity) when trying to build light for a level that's only got 440 actors in it, almost all of which are just brick walls from Manufactura K4's Ancient Environment kit. I believe I have ~10 lights placed throughout so far, all of which are shadowless. It rests at about 80*C and 120 FPS while navigating the viewport. Is my level too big? I'd like to hope my computer could handle what's only about half of the skeleton of the dungeon, but I'm not sure what else I could be doing. Here are my specs

  • i5-4670k CPU @ 3.40 GHz

  • GeForce GTX 760

  • ASRock Fatal1ty Z87 Killer Motherboard

  • Windows 7 64-bit

  • 8 GB RAM

It's worth noting I only have the default CPU cooler installed as the EVO 212 I ordered doesn't fit in my current case.

EDIT: I popped off the side of the case tonight while attempting to build the lighting and managed to do it without breaking 100*C. I was watching my CPU and it never broke 80%, so it must just be something with my CPU cooler.

Although the thermal performance of the standard Intel heat-sink is quite poor, it's not that bad at standard frequencies. I imagine if you run Intel Burn Test (or any other application that maximises CPU utilisation), the outcome will be the same. You may need to replace the thermal paste and reseat the heat-sink.

If your computer cant handle CPUs on full usage it means something wrong with your cooling system or it simply sux (but default should really handle it if you mot overclocking), its not really UE4 problem

UE4 is the only thing that brings it even remotely close to these levels, which is why I'm asking about it here. I wasn't sure if there were others with similar specs who could tell me how their UE4 experiences have compared.

It does seem you have an issue but you should be able to reduce the local processor count in swarm to reduce the usage.
