As the others hinted, it's a symptom of some other problems you have with either hardware or software. I think it is the processor related bugs... No problem when I used option "threads=1"...

Beeblebrox Posted May 17 Share Posted May 17 (edited) 9 hours ago, GravityWorm said: I use GNU/Linux. I do not have RC + GUI. Thx! As wrathchild has posted you can still set these things in the command line/non GUI version of rc. Thing is, personally, I only ever use the GUI interfaced version of rc. Without being able to preview the conversion multiple times, (I do it 10-50 times before committing to a conversion), or very set things like colour distance from ceide to yuv, etc, you are severely restricting the control you have. One of the most important things I've learnt is being able to crank up the contrast in the GUI, preview it, tweak it, preview, repeat, etc etc until I am happy, then I start the conversion. Without this, half my conversions would look a lot worse than they came out. I've never used the command line only version of rc. For me the GUI is amazing.

+MrFish Posted May 17 Share Posted May 17 In case anyone is interested... @Sheddy sent me a few new RastaConverter binaries to test, regarding my particular CPU. As it turns out, my processor doesn't support AVX, which is a CPU extension being used in the latest build/version, but not being used in previous builds/versions. 2 Quote Link to comment Share on other sites More sharing options...

I've just been surprised to find out that the AVX and AVX2 builds actually make very little, if any difference to the speed and it is the profile guided optimization giving the biggest boost. Have added that plain x64 processor build here: https://github.com/sheddyshack/RastaConverter/releases/tag/RastaConverterBeta10-Intel-PGO 3 Quote Link to comment Share on other sites More sharing options...

SIMD optimization is typically a data reorganization problem, not a code problem. The compiler rarely makes solid gains unless you are already using data in a very applicable pattern (vectors with one to many transformations). For that matter I'm not really sure the problem set of RastaConverter is SIMD-friendly - it certainly should be thread friendly, since raster lines dont have inter-dependency. 1 Quote Link to comment Share on other sites More sharing options...

What's puzzling to me is the fall off (and even negative regression) when adding hardware threads. I would think that just subdivides the image in smaller vertical regions and each thread can run independently, so there should be some gain. Is the color comparison done perhaps in a central thread, and thus becomes a common dependency? Quote Link to comment Share on other sites More sharing options...

Cranking up the contrast will drop the background closer to black, in line with the source image, and get rid of the grey. 1 1 Quote Link to comment Share on other sites More sharing options...

On my older PC I'm seeing the rate improve from around 80,000 to mid to high 90,000's. If you're interested, please give it a go. I am kind of curious what sort of rates Stephen might get on his system given he already gets around 300,000 sometimes on YUV https://github.com/sheddyshack/RastaConverter/releases/tag/RastaConverterBeta10 Kind Regards I'm out of town until late Monday - I'll definitely give this a try when I get home! 3 Quote Link to comment Share on other sites More sharing options...

Rybags Posted May 20 Share Posted May 20 APAC? Would be interesting to see a comparison of how RC handles that frame. I think I've got the movie here somewhere. Quote Link to comment Share on other sites More sharing options...
