Godzila Posted July 30, 2016 Posted July 30, 2016 I am posting in this forum because this is not DCS related, it happens elsewhere also. Feel free to move if needed. Video is very bad, i recorded with my phone, but you should see what the problem is. I get this weird picture. I could describe it as tearing, but I don't know. It is happening at 4K resolution on relatively low end computer, but I also noticed it at lower resolutions. Does anybody know what is the source of this? Bad HDMI cable or low end graphic card (GTX 960)? It also happens with 1080p youtube videos. I googled a lot but couldn't find any info for causes of this phenomenon.
Goldsmack Posted July 30, 2016 Posted July 30, 2016 yeah that looks like screen tearing, enable v-sync see if that helps.

Godzila Posted July 30, 2016 Author Posted July 30, 2016 V-sync is enabled. It looks as it is doing fine at 30fps, it is running at full 60 only occasionally. No fps drop bellow 30 is seen with ingame fps counter when I provoke this tearing. This is not my computer, but I am trying to figure this out because I would like to go 4K sometime soon. Is it possible that low end 4K tv connected with HDMI cable isn't capable of drawing all frames? I would blame low power of CPU&GPU, but 1080p youtube video at 30 fps isn't really hard on PC and it also makes some tearing. I would first try with good HDMI cable, but there are none available locally.
Goldsmack Posted July 30, 2016 Posted July 30, 2016 Hmm..I am not sure then. I have never experienced this kind of screen tearing that V-sync didn't fix at 1080p. I have very limited experience with 4k so cannot comment on that but there are allot of very experienced people on these forums that will know more that should comment after seeing your video. Sorry I couldn't help but hope you find a fix :thumbup: Windows 10 Pro 64, I5 4690k @4.6GHz with CAPTIAN 240EX AOI, Samsung 850 EVO ,G Skill Ripjaws 16G RAM, Nvidia GTX 970 STRIX, MSI Z97 GAMING 5, WD Blue 1TB HDD, Seasonic M12 II EVO psu, Track IR 5, Pro Flight X-55 Rhino H.O.T.A.S
Art-J Posted July 30, 2016 Posted July 30, 2016 It's adorable that You've added a soundtrack even to a 6-seconds clip :D. Anyway - first - Alt-Enter to make sure the V-Sync is really working, second - 30/60 sounds like adaptive V-Sync with half-frames mode is set in NVidia control panel. You might test other modes (I use simple adaptive only), but occasional tearing on adaptive WILL happen even when the rendering drops below 60 and I'm sure it does when trying to play 4k on this underpowered card. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

BitMaster Posted July 31, 2016 Posted July 31, 2016 WINDOWS key does same thing if you dont have such extra keys like Volume on your keyboard...and I am pretty sure my Logitech VOL control keys work either way with Logitech's own pop-up.

Godzila Posted July 31, 2016 Author Posted July 31, 2016 It's adorable that You've added a soundtrack even to a 6-seconds clip :D. That was the sound from the PC trying to produce 4K image:lol: I will try alt+enter when I get to that computer. We are also desperately trying to get quality HDMI cable to try, since I still think that might be part of the problem. Thanks for the tips about checking full screen mode.
