It's working in my head.
Actually, I tested that one frame by just multiplying the RGB by 0.2 for the whole frame (because the largest RGB component is ~5.0) and the bright area looks great with no blocking or hue shift and more detail than madVR. So when I put the proper nonlinear function in place everything should look great. However, many a drop is spilt twixt cup and mouth. Or:
But, Mousie, thou art no thy lane,
In proving foresight may be vain;
The best laid schemes o' Mice an' Men,
Gang aft agley,
An' lea'e us nought but grief an' pain,
For promis'd joy!
-- "To A Mouse" by Robert Burns
