Donut Posted November 13, 2018 Share Posted November 13, 2018 (edited) I have been messing around to try and get the best performance in DCS and noticed a possible bug with anti-aliasing. With SSAA 1.5 or MSAA 2x, I get almost exactly the same FPS but I feel that SSAA looks better. No problems here. My FPS was roughly the following for each one: Sitting on the runway at Nellis in the Hornet Looking forward: FPS 103 Looking left: FPS 68 The possible anti-aliasing bug that I noticed was that when I turned off all anti-aliasing, my FPS stayed the exact same. I was expecting a significant increase in FPS with anti-aliasing turned off but that was not the case. I restarted DCS, checked/unchecked full screen, tried LALT+ENTER and got the same results. Anyone else getting similar performance and if so, does this seem right?

petsild Posted November 13, 2018 Share Posted November 13, 2018 This is a bad property of the DCS, in every direction you have a different fps. When you turn on AA it gets worse, it depends on the complexity and the number of units in the mission.

When you turn on AA it gets worse, it depends on the complexity and the number of units in the mission. I can understand that. I would expect the drop in FPS as I look to more detailed areas. In my brief test above, I saw the FPS drop as I looked left towards the hangars. My concern is that turning off anti-aliasing all together does not increase FPS. i5 7600K @4.8GHz | 1080 Ti | 32GB 3200MHz | SSD | DCS SETTINGS | "COCKPIT" Link to comment Share on other sites More sharing options...

Donut Posted November 14, 2018 Author Share Posted November 14, 2018 (edited) Did you reboot DCS between tests ? Yes, every time I changed a setting I exited DCS and restarted. SSAA 1.5 MSAA 2x Both Off I get the same FPS with both off that I do with either one of them on.

Svsmokey Posted November 14, 2018 Share Posted November 14, 2018 (edited) That's really strange . I just ran a similar series of tests after a gpu upgrade , and every change was reflected in fps . This on stable . I should add that my tests were run in-flight over the Caucasus .

Donut Posted November 14, 2018 Author Share Posted November 14, 2018 (edited) Okay everyone. Quick update here. I don't think this is a bug. I did some further testing just now and what is happening is that I have several static aircraft on the ramp at Nellis. When I take them away, I noticed the FPS increase when anti-aliasing is off compared to on. It is only when the static aircraft are present that I don't see the difference in FPS between anti-aliasing on/off. Lesson learned though...static aircraft are a huge hit on FPS Edited November 18, 2018 by =BJM= i5 7600K @4.8GHz | 1080 Ti | 32GB 3200MHz | SSD | DCS SETTINGS | "COCKPIT" Link to comment Share on other sites More sharing options...

Lesson learned though...static aircraft are a huge hit on FPS They certainly are ! Kholki has a bunch of statics , and the frame rate is in the basement . Sure is pretty , though , and i don't mind low frames while taxiing . 9700k @ stock , Aorus Pro Z390 wifi , 32gb 3200 mhz CL16 , 1tb EVO 970 , MSI RX 6800XT Gaming X TRIO , Seasonic Prime 850w Gold , Coolermaster H500m , Noctua NH-D15S , CH Pro throttle and T50CM2/WarBrD base on Foxxmounts , CH pedals , Reverb G2v2 Link to comment Share on other sites More sharing options...

Lesson learned though...static aircraft are a huge hit on FPS Static aircrafts (hornet lot 20 !!) are not really a hudge "hit on fps" but are a real issue/bug. I mean when you put some, what you see is fps AND cpu/gpu usage going down to half the normal numbers. It creates a limitation issue, but nothing to do with ressources (gpu/cpu). So I consider it a bug and not a fps hit. Link to comment Share on other sites More sharing options...

So I consider it a bug and not a fps hit. I agree, it is a bug or at least due the Hornet not being optimized. I just did a little test and changed all my static Hornets to A-10's and the FPS drop was much less. So, to sum this whole thread up, the strange FPS behavior had nothing to do with anti-aliasing, at least not directly, but was caused by the Hornet statics. I look at a Hornet and my FPS drops significantly. i5 7600K @4.8GHz | 1080 Ti | 32GB 3200MHz | SSD | DCS SETTINGS | "COCKPIT" Link to comment Share on other sites More sharing options...
OttoPus Posted November 21, 2018 Share Posted November 21, 2018 Yes Hornet statics ( and not only statics, even the player controlled ones in multi ) make FPS drop hard. Link to comment Share on other sites More sharing options...
