Want to get shadows in the Basic profiles.txt

Hi, I got a new Macbook Pro with Iris 655 graphics. Runs OK and Zwiftalizer gives me about 40 fps which is OK. So it could be good enough to run better graphics - basically I’d like to have shadows, even if I get lower framerate.

According to https://github.com/mhanney/zwiftalizer/blob/master/docs/zwift-config-file-variables-2016-12-08.md I can modify Basic as follows

res 1280x720(0x)
sres 512x512
set gSSAO=1
set gFXAA=1
set gSunRays=1
set gHeadlight=0
set gFoliagePercent=0.5
set gSimpleReflections=1
set gLODBias=1.5
set gShowFPS=1

however I’m no getting shadows.

Any ideas?



Gosh I need to turn shadows off because my mac was rocking 9 fps max on the NYC map Saturday. Can the sres be set to 0x0? My default at basic is 512x512.
