Hi,
After seaching the forum without getting the right answer, I am asking here : I just upgraded to GTX1070 on my I5 6500K (4.4 ghz OC) 8GO ram setup. I am really pleased with my performance so far as I can sustain 60fps in almost all situations. Except that when I am on the ground looking around at buildings or others aircrafts, my FPS drop at around 45 - 50 fps and panning with Trackir becomes sluggish. Is it a known issue that FPS get hit on the ground even with aircraft not powered? Or is there any settings I can tweak to avoid that? Currently my settings are : Texture : High Terrain Texture : High Civ traffic : Low Water : Medium Visib range : High Heatblur : low Shadows : medium res cockpit display : 512 MSAA 4X HDR ON Depth of Field OFF Lens effet : dirt and flare Clutter bushes : 700 Trees visibility : max Preload radius : max Af : 8X Flat terrain shadows : ON In Nvidia Inspector : I have Vsync Force ON (OFF In Game) and Sparse Grid Supersampling AA to 4X I would be glad to know exactly what water and shadows settings do? What is the difference between low, medium and high? Hope you can help me, Best regards, Pierre |

Water is a bad one. It actually runs under the entire map so it is a big hit. Set it to low. Still looks good to me. Heat blur is not worth the melted HUD screens. I used to love the blur, no more.
Best post I have seen for optimizing is in the A-10 Forum Troubleshooting section. Lot s of things to try. DCS is very subjective so find what is best for you. |

Preload radius and trees are very hardware demanding, especially on only 8GB system. Note that even default "high" preset doesn't have them on max, that's for a reason.
To compare, I still use my old GTX780, with settings pretty much as Yours except for preload and trees, which I have at default high (6000 and 9000, if I recall correctly?). On single 1200p monitor that yields stable 60 all around, with drops to 50-few at Batumi and Senaki (two most fps hungry airbases on Caucasus map). Also, Sparse Grid Supersampling has always been a frame murderer, though I don't know how much it should affect such a hefty card like 1070.

For what it's worth, playing MP in 2.5 (FS99th server), spawning in the Mirage at Nellis gave me extremely low framerate (4 fps, aka slideshow)... but closing the canopy made it back to normal.

where are you when that happens and how many placed units are nearby?
also if it's in multiplayer, if the server is already running a long time with a lot of players (from time to time they crash near airports) can cause a lot of FPS drops. Best example i have is on the Bruning skies server, where after a few hours, novo has either a lot of wrecks there or player, and both things can lead to FPS drop, but once you're away from it, the FPS get again up and stable

Hi and thank you for your help,
FPS drop occurs at Kobuleti (Warthog proficiency mission 1.2.2 by Gliptal), when looking towards aircrafts on the parking and airbase buidings in the background. You can test as it is really the begining of the misson, Aircraft powered off. 2 F16 and one UAV are starting rightaway and taxi in front of my A10. There are a dozens of airplanes at the park I guess. I confirm that I only have 8go RAM in my system. Also 8go vram in the GTX. I play only single player so I think 8go is sufficent. It seems it uses around 60% of RAM during game. I lowered water to low and dropped tree and preload radius a little. It is better but it seems that no matters what I lowers, I have this FPS drop from 5 to 10 below 60. It is sufficient to induce stutters because of Vsync (if I do not use Vsync I have screen tearing). I guess I must live with it, if it is only at parking, it may not be a big deal. I thinks it is rather inherent to game optimization. PS Is Windows task manager good enough to monitor RAM usage or do you advice another utility for that? Pierre |

Pierre,
Kobuleti is known as frame rate hungry and I guess with AI moving around even more. The tearing is a different story and the stutters. Thats not a simple frame-rate issue. The human eye takes every rate above 30 as "smooth", so your issue is something else. Just a thought: did you try it with NVidia inspector settings to stock? Sparse Grid SS killed me on my old system flying FSX there. With my actual system I do not use Nvidia tuning anymore.

There's no need to set so high. You could notice a grass from rather less distance. My setting is 300.
