Troubleshooting / Re: OS X 10.11 and CPU usage

Ok. I actually don't care so much for the font, because the game is still playable. However, the heating problem concerns me. I don't want to kill my laptop. My iMac already died a few months back soon after the system reported a broken gpu diode sensor. I will not play OpenXcom in fullscreen until I know what is going on. There must be other Mac users here. Did anyone else notice heating problems?

I think they are both getting cooked, CPU and GPU. Please look at the screenshot I posted below (same as yesterday, Intel Power Gadget). The strange thing is, that the CPU frequency stays very low in fullscreen mode - even lower than in windowed mode, although the CPU consumes 3x the energy and heats up quickly. I have no idea how this is possible and why. At the same time, in fullscreen mode, the GPU frequency is as high as it can be (it is the green GT graph). The difference here between windowed and fullscreen mode does not seem a lot, but the GPU is clearly running at 100% in fullscreen mode all the time.

I also attached two screenshots of Macs Fan Control - one before and one after a few seconds of fullscreen mode (main menu, just looking at the buttons again and not doing anything). The CPU increase is about 40 C° and the GPU is 37 C°. Even the SSD gets a little hotter, but that might be due to the whole system heating up.

Yes, it is difficult to monitor anything when in fullscreen mode. I use Intel Power Gadget to check temperature, cpu clock and energy consumption in the background.

This is what it looks like, when i switch from windowed mode to fullscreen for 30 seconds and then back to windowed mode. The temperature would have climbed steadily of course if I stayed in fullscreen. I didn't do anything in the game - I just looked at the main menu for 30 seconds.

Driver issue or bug maybe?

Does your CPU get so hot in full screen mode, that it is close to shutting itself down? What happens when you run OpenXcom in window mode? Very little heat increase I guess.

darklord42: Thanks for the info. A driver issue makes sense. I still don't have a clue, why the temperature goes up that much in full screen mode. The problem does not exist in other games, for example GZDoom. That one runs in full screen 1440*900 and the temperature stays below 40°C.

Arthanor: Thank you very much for your answer. I disabled the filter, but the look is still the same, as you can see in the attached screenshot. Only difference is, that the frame rate drops to 15. Choosing one of the other filters does not change the fonts either.

I understand the pixel conversion issue and why it can cause more cpu load. I think the retina display or the way the OS handles the resolution is the problem. Sadly, I was not able to fix it. The native resolution is 2560*1600. The OS by default can scale to 1024*640, 1280*800 (which is standard), 1440* 900 and 1680*1050. With a little tool called Retina Displaymenu you have access to all kinds of supported resolutions. I tried setting the display to the native resolution and a few others. The result is always the same: windowed mode is ok, although in 2560*1600 the cpu gets a little hot as well. In fullscreen mode, the temperature goes through the roof (especially in 2560*1600). I always set the game resolution to the system resolution. So in theory, with 1280 system and game resolution, there should be no pixel conversion that can cause that much cpu load. Instead, there should just be pixel doubleing. I guess there must be some kind of scaling going on in the background, that I don't understand - even when set to 1280.

Warboy1982: I found the vsync setting in options.cfg. It was already switched on.

Thanks for your help everyone! I played around with the settings, although without any success. Disabling the opengl filters causes even more cpu load. Changing the resolution to whatever (even 640*480) has no noticeable effect. However, running OpenXcom in windowed mode (no matter what resolution) helps a lot. Switching back to fullscreen instantly increases cpu power consumption by 200% and the temperature raises from around 60 °C to almost 100 °C (idle is between 35 and 40). I think the CPU will shut down at 105. I also tried limiting the frame rate to 30 fps or lower, also without any noticeable effect. I did not find the vsync setting.

This is what it looks like. Any ideas?

Hello.

1. I have OpenXcom 1.0 and OS X 10.11. The fonts are not displayed correctly here. Does anyone know how to fix this?

2. I am running OpenXcom on a Macbook Pro 2015, 2.7 GHZ. The CPU usage is very high and the fans kick in immediately even in the options menu. Is that normal?

Thanks for your answers!
