Sony A7III ARW files

I'm looking for culling software for newest Sony camera.
FRV looks great and is pretty fast, almost as fast as FastPictureViewer, but has same problem as latter.
RAWs zoomed to 1:1 arent sharp at all, they are better then FastPictureViewer, but only by a fraction.
Is FRV reading full raw from new Sony camera or only interpolating sidecar jpg?
Images in LR are blazingly sharp, in FRV (and FPV even more) looks missfocused...

Dear Sir:

1st: Most raw converters (including Lr) apply some sharpening on processed images as a default. FRV does not do it by default, but provides (optional) screen sharpening via 'S' key or Menu-View-Screen sharpening (two presets are tunable via Preferences - Sharpening).

2nd: RAW processing is always balance between speed and quality (including visual acutance). In FRV we use fastest possible method.

In coming FRV 1.4.7 we added second (better) demosaic method implemented on videocard (GPU).

Please try this new version (now in Release Candidate): https://www.fastrawviewer.com/blog/FastRawViewer-1-4-7-release-candidate

In this version, new demosaic method is turned on by default for modern CPUs (Intel Ivy Bridge and later) and should be enabled manually by Preferences - GPU Processing - Process RAW data on GPU for older CPUs.

To better match full-scale raw converters, we suggest to use this new demosaic together with screen sharpening mentioned above.

Hi,

Ok, this demosaic method did the trick. Awesome! Without further sharpening raws looks great, on first glance almost identical like in LR, which was the case. Great!

I dont see any lagging or slowing down. Fast and sharp - so i have to switch to FRV

Thanks!

I agree, FRV 1.4.7 renders the RAW files from my A7III very nice. I add a sharpening of 100% with 1px size.
