martyj Posted January 18, 2018 Share Posted January 18, 2018 My game has really low frame rates. Between 14 and 24 fps. I profiled my game today and the GPU utilization and CPU utilization are super small. https://imgur.com/a/IOxg4 This makes me think the bottlekneck is either memory bandwidth or PCI Express bus restrictions. Any ideas on how I can resolve these performance problems? Thanks, Marty Quote Link to comment Share on other sites More sharing options...

martyj Posted January 19, 2018 Author Share Posted January 19, 2018 @Thirsty Panther I've gone over that post often. The problems I am experiencing do not seem to match any of the issues listed. 1 Quote Link to comment Share on other sites More sharing options...
M0lD Posted January 19, 2018 Share Posted January 19, 2018 What hardware are you useing? And are you running debug mode? Cuse that slows down a little... Quote Link to comment Share on other sites More sharing options...
GorzenDev Posted January 19, 2018 Share Posted January 19, 2018 if you are using vs2017 and have heap profiling enabled it will drop your fps significant Quote Link to comment Share on other sites More sharing options...
martyj Posted January 20, 2018 Author Share Posted January 20, 2018 My hardware: CPU: AMD Ryzen 7 1700X GPU: Nvidia 980 TI. I modified by build process to optimize the build for speed and removed debugging information, and this doubles the FPS to 30-45. But considering my GPU I would expect a much higher FPS. My screen resolution is 95% of 1080p. Dropping my resolution doesn't help with framerate as well.

M0lD Posted January 20, 2018 Share Posted January 20, 2018 Ok, your hardware pretty lit. so your running a big map? Or do you have a model with extreme polycount... Are you running fine on a blank map? I dont know much about the engine btw Quote Link to comment Share on other sites More sharing options...
M0lD Posted January 20, 2018 Share Posted January 20, 2018 Is there a cap in the engine that says how much it can take on the Cpu? Else from cores Quote Link to comment Share on other sites More sharing options...
