elite dangerous performance boost/poss judder fix

[KINGvr]

hello folks

iv been playing around with a judder solution that i accidentally found a couple of weeks ago, but replicating it was problematic, however, i think iv got the instructions nailed, so lets see how we get on

what we are going to do here is force the game into 60hz low persistence, currently the game forces us to use 75hz, at 60hz we are 25% better off on gpu usage, so judder becomes 'less' of an issue, i say less because if the frame rate drops below 60, its still juddersville, however, we now have atleast 20% less work for the gpu to do, giving us greater head room.

this may not work for everyone, and some people may not like the flicker involved with 60hz low persistence



ok, this is how im configured to run elite dangerous

msi afterburner for osd monitoring
aero snap is disabled
running sweetfx with custom setting from the VR sweet fx thread, smaa is turned off in the settings file, and in game fxaa is used(thats just my preference)
rift is set to secondary display, and set to 'left' of main monitor in nvidia control panel

ok, the instructions, good luck ha

start the game, make sure everything is as it should be, 75fps, all good

save and exit

start nvidia control panel, enable DSR factors if not already done so, and enable all factors upto 4k
change resolution of rift to 2560x1440p@60hz, dont forget the 60hz bit!!! save and apply
look at rift display, everything will be messed up and dark with a flicker! it could also be very bright(60hz LP off) dont worry, should be ok(EDIT setting res to 1080p 60hz seems to work so no need for DSR amd users
now, make sure both elite dangerous launcher and NCP(amd ccc) are in the centre of your display
goto 'set up mulitple displays' in nvidia control panel(not sure of option in CCC), and make rift 'primary' display and apply, at this point youll have to use 1 eye to peek at the rift to see the NCP, you can now drag the NCP onto your main monitor but leave the ED launcher on the rifts display

start ED
image will appear on your monitor but in 'rift' mode(duel image with head tracking), this is good, navigate to options once in game

at this point note the 'state' of the refresh rate and fps limiter options, they should be 'reded' out, if so were cooking on gas, if they are white, dont worry, continue on
ok, change monitor to 'primary' in game options and apply, the refresh rate and fps limit should now be 'white' in options
image should now come on rift, and using you OSD should now be 60fps, and 'darkish' indicating 60hz Low persistence is ON and working, if the image is very bright, LP is off, and you will see a blurring of everything
you can now test the game, however, i believe it to be better, and even smoother when rift is set to 'secondary' display, but theres not much in it, so have a good go of the game at this point if 60hz LP has been achieved

so, moving on for those who didnt get the correct options or low persistence working, or want to make rift secondary display for even more buttery goodness
exit game
make main monitor 'primary' in nvidia control panel and apply
restart game, do the same as above, just change display in game options to 'secondary' and save, hopefully, your now at 60hz with LP on, if LP is off(display very bright) try changing resolution ingame, and it should turn on, then change resolution back to desired res, this usually works, but only when rift is secondary display for some reason

if it hasnt worked, try again, just repeat the process, sometimes it can take a couple of goes to get the in game options to trip out and allow LP

the results for me have been quite profound, although 60hzLP isnt quite as good as 75hzLP for the low persistence side of things, there seems to be a more fluid action to the actual game rendering, head tracking has always been good for me, but i didnt realize how much micro stutter was going on until i played at 60hz, again, this just may be my setup

my ingame settings are

resolution x1.2 dsr(nvidia control panel with smoothing set to 20%, again, my preference)
AO off
blur off
bloom off
AA fxaa
low/medium shadows(ultra if im not in RES)
effects low
everything else high/ultra, again, your preference really

i know its abit long winded, iv just tried to make it clear for everyone to understand and have a go at, in real time it takes 2mins to do

hope it helps someone
any problems getting it to work, post below and well see what we can do
anyone who finds a better way of getting the game to allow 60hz let us know below

peace



iv also posted this on the ED forum, but mods keep moving it

KINGvr,

Thanks for the tips! Just started running Elite on the DK2 last night and I was looking for some hints to get it running better on my system. If you force 60hz at 1080p would you get similar results? I have an AMD 7870 which does not support VSR/DSR.

If you have it handy, could you post a link to the thread you referenced with the VR sweet fx settings?

Many thanks!

hello mate

iv been banned off the ED forums for having a pop at an over zealous mod hahaaa

lets see if we can help

the main reason for setting DSR to 2560x1440p was it help replicate the bug 99% of the time however, i was messing around for over a week before i found this

i think the key is to just set the refresh rate of the rift to 60hz@1080p, dont use 990x1080p
just do the steps and set res to 1080p@60hz and it will eventually work

this is the sweet fx link, copy and paste the 2nd set of code into the settings file of sweet fx, it will over write everything, then iv changed smaa to off(0) in the settings and use in game fxaa

hope this helps, would be nice to see how AMD users get on as im having a 390x as soon as they land 😉

nice hud colour change that will help with the txt

i can confirm that changing the resolution for rift desktop to 1080p@60hz enables the in game bug

after switching the rift to 1080p, LP was off, and the screen was very bright, however, once rift was changed to primary monitor in Nvidia control panel, 60hz LP was on and working

however, id repeat the process to get the rift as secondary monitor as it seems smoother

if you still get judder, turn off your wireless mouse if you have 1, and are not using it to control the ship

hope this helps
