Shibbyland Posted April 21, 2020 Share Posted April 21, 2020 Hi All, Upgraded my PC recently, 32GB RAM and a much more powerful GPU. Well and truly able to run DCS on reasonably high settings except for one aircraft...the MiG-21 with the RADAR on. Does anybody know what I can tweak to prevent that happening without ruining the appearance of the rest of the game? When I first bought the MiG I didn't have these issues.

Rei.BleacH Posted April 21, 2020 Share Posted April 21, 2020 Same for me, when the radar see the terrain fps go down so much impossible to game Link to comment Share on other sites More sharing options...
BadHabit Posted April 22, 2020 Share Posted April 22, 2020 Experiencing the same thing but only in the viggen. Mig's radar is fine for me.

ALLynil Posted April 22, 2020 Share Posted April 22, 2020 Wow just learning this bird. Radar fps is absolutely horrible and to be honest not acceptable every few seconds frames drop by 40ish. to mid 30s. With track ir it is close to unplayable. Playing on R 5 3600 and 1070 Ti. Is there fix planed or anything for it ? Link to comment Share on other sites More sharing options...
rinkerbuck Posted April 22, 2020 Share Posted April 22, 2020 Same here. Been reported multiple times in multiple places and I can't find any evidence the devs are working on it or even are aware. Link to comment Share on other sites More sharing options...
Hiromachi Posted April 22, 2020 Share Posted April 22, 2020 We're both aware and working on it for a while now. Since there was nothing to further say about that, I did not comment.

Shibbyland Posted April 23, 2020 Author Share Posted April 23, 2020 We're both aware and working on it for a while now. Since there was nothing to further say about that, I did not comment. Once I know that fix is coming, I will bring the news ;) Hi Hiromachi, Thanks for commenting. I did a lot of trialing with different graphics settings yesterday to see how if I could find something which made it better. High vs low settings made no difference. The framerate dropped to around 20-30 at times with RADAR on even with low settings. I am typically achieving 100+ FPS on mostly high settings with the RADAR off. Also, I didn't have issues back when I was using a Nvidia GeForce GTX 970 but have recently upgraded to Nvidia GeForce RTX 2060 Super. If it helps, RAZBAM's MiG 19 also has framerate drops with RADAR on but they are nowhere near as severe. Also, the MiG 19 has an option in the settings to have the RADAR give a static display as oppose to dynamic display. This purportedly eliminates FPS drops due to RADAR. Is it possible for you to implement something like that? Link to comment Share on other sites More sharing options...
Hiromachi Posted April 23, 2020 Share Posted April 23, 2020 We did not have those issues with radar performance until some time ago. If this is affecting other modules than it could be some issue of more general nature. Still, I dont want to speculate but will forward your input ;) AMD Ryzen 5900X @ 4.95 Ghz / Asus Crosshair VII X470 / 32 GB DDR4 3600 Mhz Cl16 / Radeon 6800XT / Samsung 960 EVO M.2 SSD / Creative SoundBlaster AE-9 / HP Reverb G2 / VIRPIL T-50CM / Thrustmaster TPR Pendular Rudder Pedals / Audio Technica ATH-MSR7 Link to comment Share on other sites More sharing options...
Shibbyland Posted April 23, 2020 Author Share Posted April 23, 2020 Well hopefully there’s a resolution soon, I like the MiG 21 and for a time was able to use it without issue but at the moment it’s unuseable for some of us. Link to comment Share on other sites More sharing options...
WildBillKelsoe Posted April 28, 2020 Share Posted April 28, 2020 I would like to add my voice to this problem as its happening to me as well. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.

alexbap Posted April 28, 2020 Share Posted April 28, 2020 I have a GTX1060 (6GB) and on Persian map and I don't have frames drop using radar. Tested low altitude over city. Today, if I remember, I'll try on Caucasus over trees. I'll also post my graphic settings so you can compare. Could this be because of radar reading trees? They are very heavy on system just for displaying them. Imagine calculating radar bouncing.

Ivan Joukov Posted May 6, 2020 Share Posted May 6, 2020 Same problem here on OB. Is the problem on stable too ? Link to comment Share on other sites More sharing options...
Brown Floyd Posted May 7, 2020 Share Posted May 7, 2020 My apologies if this has been posted already, but the issue appears to be with certain recent Nvidia graphics drivers; this is why some people have said they don't see any framerate drop. If you roll your system back to an older-but-still-recent driver (I'm using 442.19, for example), the problem will go away with no noticeable negative effect on performance in DCS or other games.

Shibbyland Posted May 7, 2020 Author Share Posted May 7, 2020 You win this thread Brown Floyd, at least for me that's made a huge difference (360% improvement in performance). Fingers crossed it doesn't wreck my performance of other games I play but the MiG 21 is flyable again. Cheers Link to comment Share on other sites More sharing options...
enigma6584 Posted May 24, 2020 Share Posted May 24, 2020 This is happening on "Stable Release" as well. I have not yet tried rolling back Nvidia drivers and currently I am using the most recent. Link to comment Share on other sites More sharing options...
Schmidtfire Posted May 24, 2020 Share Posted May 24, 2020 I can confirm. Im sitting on a high-end system (i7, 32GB RAM, nvidia 1080ti 11GB gfx card, SSD). Radar on KILLS the framerate. Radar standby or off returns framerate to normal again. Please fix. Link to comment Share on other sites More sharing options...
Hiromachi Posted May 24, 2020 Share Posted May 24, 2020 Yes, thats precisely what we're trying to do with new radar / gunsight system but as stated in an update, we need EDs cooperation in order to provide actual solution and fix. Temporary solution is to revert to older Nvidia drivers. I fly in VR and I'm using 442.50 from Feb which seems to help a lot.

Hiromachi Posted May 24, 2020 Share Posted May 24, 2020 Whoever is experiencing it and notices solid FPS drop, please provide the track if possible. Just a short track from flyby when you try the radar on /off. We need it for internal review.

Hiromachi Posted May 24, 2020 Share Posted May 24, 2020 I have a amd rx 5700 and afaik i have not noticed any radar fps issues. Is there a specific mission one should test? It's likely specific to Nvidia GPUs. At least is associated with a change in their drivers.

sc_neo Posted May 24, 2020 Share Posted May 24, 2020 Ha Nvidia probably activated "ray tracing" for everyone regardless of having a RTX gpu and now DCS gets confused like....Whaaaaaaaat, ray tracing? feels like radar rays to me :) Link to comment Share on other sites More sharing options...
MiG21bisFishbedL Posted May 24, 2020 Share Posted May 24, 2020 I have a amd rx 5700 and afaik i have not noticed any radar fps issues. Is there a specific mission one should test? Seems to be nVidia specific, as Hiromachi stated, but if you're still interested? Just turn on the radar and point it at the ground. I'd do tests against water, open ground, and more building dense ground. Reformers hate him!
