Frame drops when moving Throttles, Rudder pedals.

I have an x-55 Rhino HOTAS, and a set of Saitek pro flight Rudder Pedals.

When I move the Throttle on the Rhino, or use the pedals, My frame rate drops below 20, sometimes as low as 5-8 FPS.

When my Pedals are centered and my throttle stays in one place, I get from rates ~60 FPS.

This started within the last week, and I've never had this problem before, even in 1.5.

If anybody could give me some idea of how to fix this, it would be much appreciated.

I have the exact same issue with the F15C.

Warthog + Saitek pedals + TIR5 + Logitech g502

Holding the controller in exactly the same place = 80-100 FPS

moving a controller brings me down to 30-50 FPS

The issue started when I re-installed the F15.

The issue does NOT occur in any of the "free" models, which makes me wonder

if this issue is DRM-related...? That would be rather ironic, would it not? :)

moving throttle, stick and pedals can bring me down to <10 FPS

[EDIT]

This issue does not happen with the Sabre, nor with the A10 - only with the F15C

Exactly. I recently got the SU-27 and I don't have any real issues with that outside of my Mode switches not always functioning, which is annoying but livable I suppose.

To clarify, it is a crap shoot if, when I move my mode switch, which I have set up as modifiers, whether or not the game will recognize the change and actually change the switch commands. I can make up for most of it with keyboard commands, but when I come in for a rearm-refuel and I can't shut my engines down, it get's a bit irritating.

i have similar problem with f-15 too, i had opened a tread for this issue on dcs f-15 section.

and recorded a track.

specially with moving ailerons causes to decrease fps

before latest update i had no problem

I think mine started before the 1.5.1 update but I'm not sure. Either way, when I shut down my X-55 Profiler the issue improved some, but not much. I dunno. Now that I have the SU-27 I've more or less left the F-15 in the hanger and the only issue left is DCS getting all squirrely with recognizing my mode switch.

Same here, I dont know what is happening but with current update, f-15 has not fun to fly.

that problem still exists with new update.

again with only f-15:(

I have this issue with the F-15 under 1.5.1 :(

Yes, me too with just purchased Bf-109k (throttle) and the F-15C is crap with or without moving the throttle (3-4 FPS every flight)

Hi, I have similar (the same?) problem, so I put it in this thread:

After 15-30 minutes of flying (Mi-8 ) sound stutters and performance drops. I thought it is because graphic card but it is caused by: Saitek Rudder Pedals. The time probably depends on number and intensity of movements. After I stop moving pedals stutters disappear and fps is normal, just like on the start of mission. Only cure for the problem I found is to put them out of USB and put it back. Then it is ok like the counter of movements was reset and it all repeats after a time.

I tried: new drivers, different USB slot, cleaning connectors but no success.

My PC specs: i5-4690K (stock freq.), R9 380 Nitro 4GB, MB Z97 D3H, Kingston 8GB+4GB 1333Mhz, Win 7 SP 1, Saitek Rudder Pedals + Cyborg F.L.Y. 5

Dear ED Developers,

this issue seems to be a global one affecting both DCS World and DCS World BETA.

The issue seems to be hard to notice on a CPU >4Ghz (e.g i7)

The issue makes the game nearly unplayable on a CPU <3Ghz (e.g i5)

Example: On my i5 750, Geforce 460, 2.67Ghz, 2xSSD, I get:

- No inputs = 80-120 FPS

- Moving a controller = 30-50 FPS

- Moving throttle, stick and pedals together < 10 FPS

- The issue does not occur on free planes (e.g the Su-25T)

- The issue occurs on all pay-ware aircrafts.

- The issue is a show-stopper, P0/S1P1 on low-mid range systems.

I think these threads might need to be joined and the issue to be looked into!

Hi,

Not sure whats changed other than the recent updates released for both 1.5 beta and 2.0 alpha but i no longer have this problem on the F-15C. Haven't changed hardware config either since initial problems so maybe one of the updates has fixed it for me?

Not tried the Bf-109K yet but will do and post if the problem still exists there?

Thanks.

I want to state I didnt notice the problem for about 5 hours of flying now. It seems the conflict was between opentrack 2.3-rc18p7 (not sure about version) and joysticks (also appeared with steering wheel). Now with opentrack 2.3-rc21p7 I detected no conflict.

which plane did you tested?

That fps lost is most noticable with f-15, you can check the fps when you move the ailerons and elevator.

I have the same problem, this occur when I set throttle during taxiing the F-15C. My joystick is an Saitek X-55.

Edit: This ocours in both 1.5 Beta and 15 stable versions.

Seen this too but not always, frame drop of ~30fps, also X-55.

here frames drop to about ~22 when I set throttles of the F-15C.

I would upgrade the PSU..600W seems a bit underpowered to me (https://www.msi.com/power-supply-calculator) . I would also check the USB hubs in which your controller is plugged and verify if it has sufficient power (http://windowstipoftheday.blogspot.ro/2010/11/windows-7-checking-usb-device-power.html).

Cheers!

750w power and similar issue here, I guess that is not releated with power supply

This is only with F-15C, then it's related with DCS World and not with power supply.

At least I think so.

Yes exactly!

I give up to flight F-15C, it's impossible. Now I have a great loss of performance :mad:

My X-55 stuff is connected through a HUB which has it's own power supply, this solved the ghost keys, i doubt the power is an issue here.

But do you steel have problems with F-15C?

Like i wrote earlier, yes i've seen this too in the F15C but not all the time.

Just tested some more, in SP didn't see it. In MP, locked brakes on the ground and throttle and it happens. Once airborne in MP it's gone.
