Default P-1 fatal error in V6.11-364 I've not seen before

Not sure how to interpret this, but it sure did stop gpuowl dead.
Windows' handling of the exception would have delayed even chaining by batch script to another instance, until the user takes some interactive action to deal with the popup.

Default P-1 on same gpu as continuing from v7.1-11 saved file with v7.2-21 gave load errors

Testing continuation of v7.1-11 written PRP file with V7.2-21 gave a burst of errors. This was on Windows 7 x64 Pro, RX480, while a V6.11-380 P-1 was running on the same gpu.

Default inexplicably long V7.2-21 iteration timings on continuation of 1257787 prp test from v7.0-40

V7.0-40 used to start the run gives ~200us/it timings.

V7.2-21 continuation on same RX480 gpu gives timings several times slower and very variable versus iteration block. This is the only task on the gpu. GPU-Z shows ~7% gpu load during this run.

Had gpuowl running on the gtx1080 as device 0 in gpuowl v6.11-380
Code:
-device <N>        : select a specific device:
 0  : GeForce GTX 1080- not-AMD
 1  : Intel(R) HD Graphics- not-AMD
 2  : Intel(R) Celeron(R) CPU G1840 @ 2.80GHz- not-AMD
Moved a GTX1080Ti onto this system, and got something like
Code:
-device <N>        : select a specific device:
 0  : Intel(R) HD Graphics- not-AMD
 1  : Intel(R) Celeron(R) CPU G1840 @ 2.80GHz- not-AMD
 2  : GeForce GTX 1080 Ti- not-AMD
 3  : GeForce GTX 1080- not-AMD
Adapted my batch files to the new state of affairs, and both gpus crunched away. This afternoon, after about 24 hours of running, Intel and NVIDIA switched again.
This derailed gpuowl on the gtx1080, and GPU-Z sessions for both gpus, but mfaktc on the gtx 1080 Ti was unaffected so far.
Code:
-device <N>        : select a specific device:
 0  : GeForce GTX 1080 Ti- not-AMD
 1  : GeForce GTX 1080- not-AMD
 2  : Intel(R) HD Graphics- not-AMD
 3  : Intel(R) Celeron(R) CPU G1840 @ 2.80GHz- not-AMD
The latest switch may have something to do with Windows downloading and preapplying updates. The NVIDIA gpu driver version appears to have changed from v382.05 to v432.00. In the attachments, the right gpu-z session has been restarted, the left has not. I have no explanation for the first NVIDIA/Intel order switch.

Your 1080 even got ray tracing support, according to your screenshots. I wonder why it thinks it has this feature...?

The new RTX cores inside Turing GPUs were essential to high ray tracing performance, not because ray tracing literally requires them — it does not — but because they represented the only way to wring acceptable real-time performance out of the feature.

That's like enabling directx 11 on dx9 cards, just to show how better the new stuff is. (or how "slow" the old one)
It produces great graphs.

This gpu is generally very reliable
The iteration times for the exponent 77936867 would have to be a little longer with the same FFT size 4M, but again with V6.11-380 a little shorter.
Can you possibly take the trouble to determine the exact value for the RX480? I accept values ​​from version 6 and version 7 (Linux or Windows) for my list, as they do not differ very much.

I enter the above value for the AMD RX 480 in the benchmark list, if you don't mind, as the deviations will probably be a maximum of 200 us / it. I just want to provide a rough guideline for the GPU-Owl users. It is not easy to get this many values, although the forum users are very cooperative here. If someone can present better values, I will of course change them immediately.
