[ RESOLVED] FPS drop with RADAR ALTIMETER on.

gulredrel · October 23, 2019

Hi Marnes23,

I can confirm your observation. Was on a longer mission in Caucasus today. Got below 5000ft AGL with radar and radar altimeter on and frame rate dropped.

Switching the radar to standby (prechauffage[?]) cured the problem and radar alt could be used. Radar in SIL mode didn't help.

Regards

Jens

Interesting. This suggests an interaction between radio altimeter and radar (code-wise) that could help understand hence solve the bug.

Will certainly try to shut off the radar next time it happens to me, so far I've only tried to shut off the radio altimeter.

Azrayen · October 27, 2019

Gave it a try yesterday and am now in a position to confirm that shutting down the radar (to PCH or Off, SIL is not enough) also allowed two mates and me to get our FPS back while still enjoying the radioaltimeter to land back at Khasab.

How is this STILL not fixed? And no confirmation from Razbam officials either after all tracks supplied.

Wizard1393 · November 25, 2019

Razbam, Care to comment? Radio altimeter is often needed, why this should be fixed. In next OB ? Otherwise very happy with the recent Mirage update. Had me play through the campaign again, albeit with the radio alt off... :)

Rgr. Hope they fix it soon.

Just got back into the Mirage for a week now, flying, making missions, testing missions and discovered this problem last night. Didn't know what it was until finding this thread. Got a track file is someone wants or needs it. Reading above users say already on RazBam's radar which is good.

But obviously wondering when this will get fixed. Kind of game killing regarding this module.

caponi · January 26, 2020

Yesterday i had the same behaviour ...

On approach to Kutaisi my FPS dropped down dramaticaly from 60 fps (vsync) to r.a. 35 fps.

I watched for my flood lights, but they were not on !

As i remember by the Radar altimeter bug i switch the Radar altimeter off ...

is not good for landing but the frames came back :music_whistling:

next experience ...

with this fps drop the flood lights do nothing with the frames !!??

if all is right, what may (individuell) cause these problems on my computer ?

i have no idea :(

all tipps from ED's forum were not succesful ...

=DECOY= · March 13, 2020

fixed

Ramsay · March 13, 2020

fixed

:thumbup: Hooray, I had became reluctant to turn on the radar altimeter.

Steph21 · March 14, 2020

Very nice news from you Razbam lately, that's great :thumbup:

Scalp · March 14, 2020

No, the bug is still there.

This afternoon, I made a flight at high altitude, arrived at low I had fall of fps, by deactivating the radio probe, the fps became normal again

Ramsay · March 14, 2020

No, the bug is still there.

AFAIK Decoy meant the bug had been tested/fixed in an internal build - the patch/fix is still to be pushed to ED --> Open Beta --> Release.

Knock-Knock · April 1, 2020

Any chance we will see this fix soon? Still happening in latest OB.

84-Simba · June 10, 2020

I knew something was wrong !

I just flew almost every WWII campaigns above Normandy and my FPS were perfect (beside the bombing runs of the B-17s)

Around 100 aircrafts in the air and the same with ground units above a proven FPS demanding map and no flaws ...

Started the M2000 and did notice that immediately.

When coming back to the homeplate FPS are dropping and some buttons and axis are not always responding immediately.

I was thinking about the new lightings ...

The bug is definitely still present on the Stable as we speak.

I tried to turn off the radar altimeter with no joy.

I'll try to switch the RDI off next time.

Damn, this bug has been reported for so long.

One more reason for not buying Razbam stuff that soon ...

The radar altimeter bug could specifically be remedied by turning off the radar alt. If that doesn't bring back your FPS, then honestly you are experiencing a different bug.

As some said in this thread,

Acting on the RDI is sometimes the solution that works, sometimes it is the alt radar.

I'll try both.

DimSim · July 3, 2020

I'm experiencing this also (I believe).

Frame rate becomes stuttery. Turning off radar altimeter improves a lot.

Seems to happen in some ares more than others. I like to leave radar alt on all the time.

EDIT: Definitely still occurs.

Just had solid repro flying over steep mountains with no other aircraft around.

Frame rate over 100fps consistently, then near mountains lots of stutter. Showed FPS on screen and saw it drop as low as 20fps (lots of variation).

Flipping radar alt off immediately smoothed fps back to 100fps. Repeated this test a few times to verify.

Was testing Instant Action Missile Combat mission after all aircraft destroyed, flying in straight line over mountains.

I got the same problem decending from high altitude to land at Tbilisi, OB SP mission last night. My frame rate dropped to lowest 7 with altimeter on. Switching Altimeter off restored the frame rate.

Still an issue (open beta v2.5.6.54046) as far as I can tell. Exactly as described on Syria Map for me today.

myHelljumper · September 7, 2020

I made a discovery regarding this bug, when your FPS drop, you can disable your radar (AA radar in A position) and the FPS will be back up again. When it's in the EM or SIL position is tanks the FPS.

The bug only shows when both the radar and the radar altimeter are ON.

RAZBAM_ELMO · September 25, 2020

Gentlemen, I apologize I'm getting here so late but I'd like to get this sorted quickly and rest assured this will be given highest priority. Is this still present in the latest OB patch from 23/09/2020? I am not experiencing it myself. If it is indeed still present please attach a new .trk file so I can bring it to the dev team asap.

myHelljumper · October 1, 2020

Hey guys, has anyone been able to reproduce this bug lately ?

I've not seen it for some time so I was not able to make a track....
