Update/ follow up to:
It seems many of us have been dealing with the Traktor Pro Blurry Waveform crash lately with both Mac and Windows and with or without NI gear. This has been officially filed under reference TR-572 by the NI team. From my experience, crashes have usually happened about 20- 30 minutes in, but for others, it has happened up to 2-3 hours in making this bug a "Sword of Damocles" situation.
Happy to update that this weekend, for the first time in a long time, I did not have a crash during a live set.
What I did:
1. Turned off Multi-Core Processing in Traktor Pro (to optimize GPU usage)
2. Turned off parallel waveforms view to essential view in Traktor Pro (to optimize GPU usage)
3. Set sample rate to 48000 HZ in Traktor Pro (optimal rate for Pioneer DJM)
4. Set buffer size set to 512 MB in Traktor Pro (to optimize CPU/ core audio usage)
5. Turned off Wi-Fi, Bluetooth in Mac OS (to optimize CPU usage)
6. Turned off Pro Motion and made display 60HZ in Mac OS (to lower GPU usage)
7. Set USB suspend setting to Disabled in Mac OS
8. Placed USB Allow accessories to connect to Always in Mac OS
The logic behind this “shotgun” approach stems (no pun intended) from the research of DJ @Spekulos from NI Community forums who was able to reproduce this bug effectively. According to Spekulos: "On my system, it's the GPU that's causing Traktor to crash. There's a faulty driver implementation (it's a known issue) that causes the switch between the integrated and dedicated GPUs to sometimes trigger a micro-freeze/micro-deadlock." Essentially when there is a micro-freeze, whether its related to the GPU or USB drive connection or the core audio driver, usually Traktor recovers, but it seems the recovery mechanism is flawed in mid versions of Traktor Pro 3 all the way up to the latest versions of Traktor Pro 4. This unfortunately results in a catastrophic crash (and an embarrassment) for us live DJs.
Will continue to monitor and report findings here.
