flaviossa Posted September 11, 2016 Share Posted September 11, 2016 Hi!! I need some info/help from you guys if it´s possible. I just migrated from a system with 2 EVGA Nvidia GTX 980 SC in SLI to a single EVGA Nvidia GTX 1080 SC. The process was simple and everything worked as it should, except DCS World :cry: I started DCS after the migration process and preserved the video parameters used before with the SLI. I was expecting a little loss of performance, but the difference was HUGE! The loss of FPS is between 12-17FPS going to 20FPS in some scenarios. Imense sttuters everywhere. So, went to work and did a downgrade in the visual parameters and got a more-or-less 30fps stable. My question is: is this correct? I´m missing something? The performance loss is that great? I was expecting some but not that! May i add, that i have lots and lots of simulators and games (Including FSX and P3D for example) and they performed very well as expected. Any hints of what i may be doing wrong? Thanks in advance!

Art-J Posted September 11, 2016 Share Posted September 11, 2016 That sounds a bit too extreme. What resolution do You use? I would also delete old options.lua (with all leftovers from the old config hidden in it) and start setting up the game options from scratch. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

flaviossa Posted September 11, 2016 Author Share Posted September 11, 2016 I´m running at default monitor res. 1920x1080 in a single monitor. No DSR in here. I´ll try your suggestion about the lua file, thanks!

Art-J Posted September 11, 2016 Share Posted September 11, 2016 Something's definitely wrong then (maybe with the drivers / driver settings?), as You should absolutely have a better fps performance. I never had an SLI setup, though, so I don't know what's the best way of converting to single, from drivers cleanup and installation point of view. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

derfritz Posted September 11, 2016 Share Posted September 11, 2016 Thats an insane loss in fps, check drivers and that you are not using the integrated cpu graphics unit Gesendet von meinem D5503 mit Tapatalk Link to comment Share on other sites More sharing options...

flaviossa Posted September 11, 2016 Author Share Posted September 11, 2016 Yep, i know something is wrong. That´s exactly what i´m searching for. The driver is a fresh new instalation 372.70 Art-J, i´m unable to find the file options.lua. Can you show me the directions? Thanks!

cthulhu68 Posted September 11, 2016 Share Posted September 11, 2016 Are you aware of the "radar bug" introduced on recent patch that causes FPS drop and stutters when using radar on M2000 and F5E (and possibly others)? Link to comment Share on other sites More sharing options...
flaviossa Posted September 11, 2016 Author Share Posted September 11, 2016 Thanks guys! I think i discovered the issue. I have just unchecked the "Mirror" option and my FPS boosted up to 70+fps in VC and 120+FPS external view (vsync off). I think the issue is over now. I really don´t know why i left the mirror option on as i had previous problem with that in the past. Anyway, i think it´s ok now. I´ll do more tests to see. Thanks for everybody that helped!
