sgibson Posted July 16, 2013 Share Posted July 16, 2013 Hi, I haven't started DCS (A-10) for maybe one or two patches and now got back as I purchased UH-1. On an empty map (no units) I get between 25-30fps even in dense environments (e.g. cities, airports, ...). Now when I have a couple of units, such as at the end of UH-1 first campaign mission or in the UH-1 weapons training my fps drop to 5-10fps. If I look away from the units the fps jumps back to 25-30fps. Any idea what I could tweak?? My system: 2,30 gigahertz AMD Phenom 9650 Quad-Core, 4 GB RAM ATI Radeon HD 6850 1 GB DDR RAM My settings: Textures: Medium Scenes: Medium Civ Traffic: Off Water: Low Visib Range: High Heat Blur: Off Shadows: Low Resolution: 1920x1200 Aspect Ratio: 16:10 Monitors: 1 Screen Res. of Cockpit: 512 MSAA: 2x HDR: Off Clutter/Bushes: 0m Tree Visibility: 2223 Preload Radius: 80876 Link to comment Share on other sites More sharing options...

ED Team NineLine Posted July 16, 2013 ED Team Share Posted July 16, 2013 Have you tried turning of Anti-Aliasing all together, make sure its not set in your video card settings? Also, are the units smoking or burning when you have the issue?

Rusty_M Posted July 16, 2013 Share Posted July 16, 2013 2.3GHz seems a bit slow for DCS The world is going mad. Me? I'm doing fine! http://www.twitch.tv/rusty_the_robot https://www.youtube.com/user/RustyRobotGaming Link to comment Share on other sites More sharing options...
HiJack Posted July 16, 2013 Share Posted July 16, 2013 The AMD CPU is part of the problem and needs replacement. Go Haswell, Intel® Core i7-4770K Processor ;) Link to comment Share on other sites More sharing options...
Tone71 Posted July 17, 2013 Share Posted July 17, 2013 Dropping the visibility range will net you a few more frames but yes, your cpu does seem rather slow for DCS (and it makes no difference that it's quad core I'm afraid).

SkateZilla Posted July 17, 2013 Share Posted July 17, 2013 (edited) The AMD CPU is part of the problem and needs replacement. Go Haswell, Intel® Core i7-4770K Processor ;) AMD isnt the problem.. (edit: i misread that as an ForgetAMD Go Intel statement, completely forgot his original specs.. ) However... In Light of his current specs. A First Generation Phenom X4 at 2.30 Ghz is incredibly weak for a DCS Engine that has everything but sound crammed into one thread. On that note. Drop Scenes to Low, and try turning MSAA off.

sgibson Posted July 17, 2013 Author Share Posted July 17, 2013 I played around with the settings in the UH-1 weapons training mission. None of them delivered a performance gain. I understand that my CPU seems to be a bottleneck (noticed that in A-10 context earlier). However, I don't get the CPU issue in this particular case. Looking at units is a performance drop. Looking away from units doubles the FPS. I also noticed that when 1 unit is in view FPS is ok - if there are multiple in view FPS drops more than half. That must have something to do with rendering objects which in turn should be done over the graphics card and not the CPU!?!? Link to comment Share on other sites More sharing options...
SkateZilla Posted July 17, 2013 Share Posted July 17, 2013 the CPU still feeds the GPU Windows 10 Pro, Ryzen 2700X @ 4.6Ghz, 32GB DDR4-3200 GSkill (F4-3200C16D-16GTZR x2), ASRock X470 Taichi Ultimate, XFX RX6800XT Merc 310 (RX-68XTALFD9) 3x ASUS VS248HP + Oculus HMD, Thrustmaster Warthog HOTAS + MFDs Link to comment Share on other sites More sharing options...
whartsell Posted July 18, 2013 Share Posted July 18, 2013 (edited) follow this guide and it will help you identify your bottlenecks... http://forums.eagle.ru/showthread.php?t=107551 if you have any questions lemme know. my gut feeling is based on your specs that your cpu and vram may be the limiting factors here. i have a 6970 and with 1920x1840 i burn up most(all) of my 2GB vram if you dont have enough Vram your system will have to transfer stuff from system ram to the video card more often which can affect performance, EDIT: I just noticed that you only have 4GB of system ram as well...on my system i use about 3.8-6GB of commit for the sim...so you should also check if you are swapping and how badly. i use radeon pro to check out my GPU Vram values while flying EDIT: another great tool is process explorer from sysinternals...it will show everything including GPU metrics Edited July 18, 2013 by whartsell Arduino,EOS and Helios Tutorial Static ATC menu mod Link to comment Share on other sites More sharing options...
