Python Posted September 24, 2014 Share Posted September 24, 2014 (edited) Hi guys, I have been playing around with Dxtory this week in the hope of recording some DCS videos, my results have been less than pleasing while recording at 1920x1080. DCS world is installed on my SSD along with Windows and Origin, everything else is on my HDD which is a decent seagate barracuda 7200 1tb drive. The write speed last tested at 80 MB/sec which didn't give great results during recording. It would slow down the game some what, but during playback of the recorded footage it was so laggy that it was pretty much unwatchable. I ran a defrag hoping it would speed things up and tested my write speeds again, my SSD went up in speed but to my surprise.... Clearly this is why I'm getting laggy playback when recording to my HDD, it simply can't keep up. My SSD is much better going on the two quick tests I did, but it is only small which is why I don't want to record to it really. I have 61GB space remaining on the SSD, 314GB on the HDD so they aren't full. Does anybody have any idea why my HDD may be so slow? I turned off all other programs, even froze my Avast during testing. Or am I going to have to invest in a second larger SDD sooner than I hoped to dedicate to DCS and recordings? My specs... Core I7 3770k at 4.4GHZ EVGA GTX680 SC Asus Sabretooth Z77 motherboard 8GB Corsair XMS3 ram (1600MHz) Corsair Force 3 SSD Seagate Barracuda 1tb HDD I'm using the Lagarith lossless codec during recording, file sizes are generally large even for short recording sessions, I don't want to drop the resolution down but may have too. Any help speeding up my HDD appreciated, many thanks. Edited September 24, 2014 by Python [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Fabri91 Posted September 24, 2014 Share Posted September 24, 2014 80MB/s for a mechanical drive isn't terrible at all. Can't you turn down some quality settings of the recording software or toy around with some compression? More than 80MB/s of video seems to be a very high amount of data for it.

Python Posted September 24, 2014 Author Share Posted September 24, 2014 That's the problem, it is now at 43 MB/s since the defrag, no idea why. Playback was poor at 80, at 43 it is useless. I'm going to try a few different codecs later to see if they make a difference. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
golani79 Posted September 24, 2014 Share Posted September 24, 2014 How large are the files you are playing back? Have you tried other codecs or do you need lossless? >> DCS liveries by golani79 << Link to comment Share on other sites More sharing options...
Rhinox Posted September 24, 2014 Share Posted September 24, 2014 Hard-drives (not SSD!) do not have constant transfer speed over its capacity, because they have more sectors on the outside tracks ("cylinders") than on inner. With constant rotational speed, read/write speed ratio can be even more than 2:1. So one way how you can maximise transfer-rates is to re-partition your drive: remove all partitions, and create new one, on only 20-25% of the first sector-numbers (AFAIK, all SATA-drives count sectors starting on the outside cylinders, so sectors with lowest numbers are those where transfer speed is highest)...

Python Posted September 29, 2014 Author Share Posted September 29, 2014 I have just found a solution... Nvidia Shadowplay! Can't believe I have waited until now to try it. Barely any performance hit what so ever, and quality is perfectly fine for what I need. To think I was about to spend £200 on a new second SSD...
