Seems like its oversampling

Bounce limit 5. Min shadow samples: 4, max shadow samples: 64. 30 seconds

Now with adaptive sampling, 4 min samples, 64 max samples, takes 23 seconds

Forgot to add jitter. With 16 samples hard coded, it takes 23 seconds I havent done the glossy stuff yet

Kind of soft shadows. Banding issue

Got the light sphere to render. Only like 5 hours into this project...

Result from just getting the miserable starting code to compile. Nothing new implemented yet
