enigma6584 Posted May 25, 2020 Posted May 25, 2020 (edited) Please provide a track from the stable release, so that we can send it to ED Attached is the track. My specs are as follows: Intel Core i9 7920X @ 2.90GHz RAM 64.0GB Graphics NVIDIA GeForce RTX 2070 In the track I've flown low level with radar on. You can see the frame rate drop clearly. I've also flown low level with radar off and you can see the frame rate go up with smooth frames all around. I've then flown jumping back and forth with radar on, radar off and you can see the switch in frame rate. Hope this helps.Mig-21BisRadarBugTest.trk Edited May 25, 2020 by enigma6584
enigma6584 Posted May 25, 2020 Posted May 25, 2020 Also, IIRC this was happening to the Mirage-2000C module as well.
sora_061 Posted May 25, 2020 Posted May 25, 2020 I have also noticed same issue. Same problem in Jf-17 and Mirage also(ground radar on and being close to ground). I have downgraded to Nvidia driver 441.87 due to SA Page in Hornet had Massive FPS drop in earlier Open Beta. Should I downgrade Nvidia driver again. Sent from my Redmi K20 Pro using Tapatalk
mdee Posted May 29, 2020 Posted May 29, 2020 Same issue with the radar. Frames drop from 120fps to even low 20 when looking at the ground. Jet is unplayable. Nvidia card.
TLTeo Posted May 29, 2020 Posted May 29, 2020 Can confirm that this is related to Nvidia. I just tested on my own RX 5700, and I saw no unusual drop in frame rates. I do lose FPS in the Mirage at low altitude, but I think that's due to the old radar altimeter bug, not the radar. Turning the radar on silent does nothing to mitigate that.
rinkerbuck Posted May 29, 2020 Posted May 29, 2020 Hmm never ever noticed any slowdown with the M2000 radar. I always thought this was related purely to ground clutter display on the Mig21 radar (or maybe other radars too). The M2000 doesnt show ground clutter though. Also the F5 does display ground clutter but has no fps issue. I initially thought the Mig21 radar was fixed in the latest patch but its still doing the slow down, just maybe to a slightly lower extent. Still really bad though. I guess I'll have to try rolling back drivers

Turning the radar on silent does nothing to mitigate that. Yes, you are correct. Now I remember that was the issue with the Mirage-2000C. I also remember the quick fix was to turn the altimeter off or something for a few minutes start it back up later IIRC but not sure. Hmm never ever noticed any slowdown with the M2000 radar.

SignorMagnifico Posted June 4, 2020 Posted June 4, 2020 The update to the MiG-21 released today was pretty great! I really enjoy the new afterburner effects and over wing vapor effects. However, the RADAR issue has not been fixed. I am also experiencing about 50% FPS loss when the RADAR is turned on and any portion happens to be pointing at the ground. Hope this gets fixed soon.

Mikaa Posted June 4, 2020 Posted June 4, 2020 Not sure if this is already known, but as I was doing some testing, it appears that there's some weirdness with the GPU/CPU utilization when the radar is turned on. My GPU drops from 95%+ down to <30% utilization when the radar is flipped from STBY to ON. At the same time, core 16 on my CPU jumps up in utilization near 90-100%, and both appear to have some oscillations in % usage. I can even hear it as the GPU fan ramps down as the radar is turned on. Not sure exactly what this is indicating, but Hopefully this helps with troubleshooting, whether ED or 3rd party dev.Mig-21 Radar Bug.trk

Same here. The MiG-21 is not usable like that. 1./JG71 "Richthofen" - Seven Eleven
MiG21bisFishbedL Posted June 6, 2020 Posted June 6, 2020 If you're on an nVidia chipset, try downgrading to 442.19 drivers. It solved it for me. As far as temporary solutions, it isn't the worst.

freehand Posted June 8, 2020 Posted June 8, 2020 So why has this not been fixed the mig is horrible at low frame rate ?

Turning off radar and Ground clutter filter and then turning on fix the issue. I'll try providing video, since trackfile would'nt be useful Sent from my Redmi K20 Pro using Tapatalk
karasinicoff Posted September 29, 2020 Posted September 29, 2020 Sep/2020 still Mig 21 has the terrible frame drops with Radar on. Anyone can report this issue again please??
Maxthrust Posted October 1, 2020 Posted October 1, 2020 I had the same problem during the free trial, otherwise I had the most fun with the Mig-21. Note to devs; please let us know when this is fixed so I can purchase ;)
Schmidtfire Posted October 4, 2020 Posted October 4, 2020 I don't care if it is fixed by Eagle Dynamics or Leatherneck. The radar is the primary sensor of MiG-21bis and it has been an ongoing issue for a long time now. This really needs to be solved.
enigma6584 Posted October 15, 2020 Posted October 15, 2020 Yep, just tried it in the Syria map myself and holy moly does the frame rate drop when I turn the radar on. I was at 3000 meters altitude.

Eber Posted November 2, 2020 Posted November 2, 2020 First of all, THANK YOU! I am new to the Mig-21. I was completely shocked about the Radar-fps-issue, but the 442.50 Driver rollback saved me. Thanks! :)
Clean Posted November 3, 2020 Posted November 3, 2020 I am also experiencing this problem. When radar is activated it seems to drop my GPU usage from 99-100% down to around 30% according to task manager. I am running a Gigabyte 1070 G1 Gaming.
DarkStar79 Posted November 4, 2020 Posted November 4, 2020 Same problem here! Just started playing the Mig-21. And i cant play it atm cause of the horrible framedrop.
LCO489 Posted November 4, 2020 Posted November 4, 2020 Maybe someday they to solve this problem :( Maybe someday, but its not today. Another OB patch without fixes for the MiG-21.
