Waltan Posted May 9, 2020 Share Posted May 9, 2020 I've been playing the P51 bluenose campaign an getting massive FPS drops down into single figure when it gets busy with the bombers. I checked my CPU , GPU and RAM usage during the drops and my CPU is at about 50%(1 thread at about 80%) capacity, my GPU at 60% and using 10GB of my 16 GB of RAM. Can anyone shed some light as to what the bottleneck in my system might be? Admittedly I am running on 1440 resolution but with the setting quite low but I cant understand why one of the 3 components isint at 100% before the frames drop. PS im pretty non tech savvy. I have an i5 8600k CPU OC to 4700mhz. A 1070 GPU slightly OC'd and 16GB of DDR4 RAm at 2133MHz. Any advice greatly appreciated. Link to comment Share on other sites More sharing options...
The_Nephilim Posted May 10, 2020 Share Posted May 10, 2020 Hi Well your system seems capable just one thing try running your XMP PRofile for your Ram. you can find that setting in BIOS.. Plus maybe you are hitting your 16gb limit of ram when those objects come in.. 32gb is reccomended these days..

Reflected Posted May 10, 2020 Share Posted May 10, 2020 (edited) Hi Waltan, 1) Your PC should be able to run the game fine in 2.5.5. Even I could, on a laptop. With 2.5.6, a massive FPS hit came when there are lots of units. The devs are aware and working on it. 2) In the meantime, you can remove some of the bombers by using the F10 radio menu right after spawning at the beginning of the mission. 3) I just submitted a campaign update to ED in which this option optimizes performance even further. I hope it will make it into the next update. Edited May 10, 2020 by Reflected Facebook Instagram YouTube Discord Link to comment Share on other sites More sharing options...

It seems that even at 10fps im only using 10GB of my available RAM and its not being used by anything else. :( . Ive allocated 16384 to the pagefile on my ssd.

I just cant understand why my system is dropping FPS when it appears no one component is showing as maxed out! CHeers anyway.. will get rid of a few bombers, its a shame cus they look awesome in formation. Link to comment Share on other sites More sharing options...
Hoirtel Posted May 11, 2020 Share Posted May 11, 2020 (edited) Have you optimised the nvidia settings? Max performance and all those other control panel settings - most cards have fans set low speed to keep noise down but this means they throttle earlier than they need to. I have set a custom fan speed for mine and yes it makes a noise but I am getting every last bit of power out of that card. Also you say your CPU and GPU are OC'd but have you checked if/when they are hitting power limits? Worth checking how long/often you are getting your CPU OC'd MHz as this can vary depending on mobo settings Edited May 11, 2020 by Hoirtel Link to comment Share on other sites More sharing options...
rinkerbuck Posted May 11, 2020 Share Posted May 11, 2020 TURN OFF WAKE TURBULENCE. It absolutely destroys FPS when there are large number of planes flying together. Link to comment Share on other sites More sharing options...
Hoirtel Posted May 12, 2020 Share Posted May 12, 2020 TURN OFF WAKE TURBULENCE. It absolutely destroys FPS when there are large number of planes flying together. Worth noting! Hadn't thought of trying that. Link to comment Share on other sites More sharing options...
dis80786 Posted May 13, 2020 Share Posted May 13, 2020 TURN OFF WAKE TURBULENCE. It absolutely destroys FPS when there are large number of planes flying together. Do this. But also, when they drop all of their bombs... well, they just haven't designed the CPU that can compute all that on one core and give decent performance too.

Have max power at 125% Have a custom fan setting but it never gets hot anyway. When i do a stress test the GPU runs 100% Stressed the CPU also and it gets full MHZ.

It never seems to hit 100% on any single core which is the bit i find strange. Runs about 85% on the busiest core. Maybe its an OC setting for individual cores.
