Hi,
I am running stepmania on linux on a ZOTAC CI320 Nano machine ( specs: http://www.zotac.com/products/mini-pcs/product/mini-pcs/detail/zbox-ci320-nano/sort/starttime/order/DESC/amount/10/section/specifications.html ) which uses an integrated graphic card ( Bay Trail as it seems to be called ) and I am having wired results.
First the issue I face is that I see framerate drops during songs but I can't really find why.
I initially tried to run stepmania directly on X11 without window manager but it just does not work (someone mentioned a focus issue and I think it's right since stepmania gets no input even from the keyboard), next I tried using i3, a very minimal window manager and it fixed the focus issue.
So Now what I checked/tried !
First I checked that the correct driver was used, it is, I downloaded the official drivers from Intel which mostly included things I have no idea what to do with but there was a small utility which shows the GPU usage when run inside the archive !
Using this tool alongside "top" in another console I launched stepmania to look at the CPU/GPU usage and the results are puzzling...
On the CPU side it is a quad core but it looks like stepmania uses at most 2 maybe 2.5 but none never go further than 70/80% and on the GPU side the usage is even lower so I don't really know where to look at :(
Another srtange thing is that I first tried at 1080p (I forgot to mention the zotac is connected to a TV screen) and then tried 720p but as far as I can tell the framerate drops are the same, the framerate is slighty higher but not by much and it drops in the same way.
Any idea where I could look ?
