There you have it Devs of the world, it's that easy to make the Series S version.
Do you PC game? This kind of game changing information is quite previlent there.
Here's a snippet of Dirt Rally 2.0's setup:
<graphics_card rating="4">
<eyefinity force="" osd="" />
<stereo enabled="false" separation="0.015" convergence="0.5" />
<resolution width="2560" height="1440" aspect="auto" fullscreen="1" vsync="1" refreshRate="60" multisampling="8xmsaa" supersampling="1" taa="1" />
<gamma level="1.0" />
<hdr level="1.0" />
and here's a bit I modified for Series S
<graphics_card rating="4">
<eyefinity force="" osd="" />
<stereo enabled="false" separation="0.015" convergence="0.5" />
<resolution width="1600" height="900" aspect="auto" fullscreen="1" vsync="1" refreshRate="60" multisampling="8xmsaa" supersampling="1" taa="1" />
<gamma level="1.0" />
<hdr level="1.0" />
I think you're under the delusion that the Series S needs major reworking. it doesn't. it just needs the resolution reducing and at a pinch taxing features turning off.
