Just adding another data point to an old thread. My DCT also gets slow to shift after 20-30 minutes of hot laps. This was during a 90 degree very humid day at Barber, running 1:48's. The car got to the point that shifting was taking around a second per shift... (mainly delay before shifting began). No delay for the first several laps, I think it was heat related.

Oil was getting to slightly above the dot between 210 and 300.

08 DCT
S5, DSC off
recent software
36k miles, no fluid change yet

Plan to change the fluid, and if the issue arises again, bigger DCT cooler.
