Hello,
We apologize for the current GPU issues you may be experiencing on versions PhotoLab 6.9+, PhotoLab7, and PureRaw 3.6.1 . We understand that some of you have noticed a significant slowdown with applications on old GPUs (i.e. possessing less than 4GB of VRAM). Please rest assured that we are actively addressing this issue and a hotfix will be available very soon.
To provide a little background, these problems stem from an initial attempt to resolve random black images and errors observed while using the AI denoising, specifically with DeepPrime and primarily DeepPrimeXD. These issues arose as the network needed to reserve a chunk of memory on the GPU for processing tasks. If it was unable to do so, the processing of the whole or part of the image failed.
To prevent such inconsistent errors, we introduced a failsafe during the initialization of PhotoLab in version 6.9, enhanced further in versions 6.10/7 and PureRaw 3.6.1.
Essentially, PhotoLab/PureRaw attempts to reserve the required memory on the GPU and, if unsuccessful, it defaults to processing everything on the CPU.
The downside of this is that GPUs on the lower end of the spectrum are disproportionately affected.
Furthermore, we regretfully did not fully anticipate the number of users this would impact nor the extent of this impact, which not only slows down image processing but potentially other computer operations as well.
We assure you that we will be reassessing this strategy rapidly and working tirelessly to devise an alternative solution that minimizes overall impact.
We apologize for any inconvenience this may have caused and appreciate your patience.
Best regards
