Catweasel Posted November 7, 2015 Share Posted November 7, 2015 Can't believe I'm the only pilot out there experiencing a massive drop in FPS since Beta 1.5.1 FPS dropped from 40 to 6 FPS, no matter which settings I choose. This happens with the MIG21 module only. Any idea what is going on? Link to comment Share on other sites More sharing options...

theropod Posted November 8, 2015 Share Posted November 8, 2015 Same performans lost here, after hotfix 2 , i have noticed performans lost but that is the worst one i think. before latest update,left alt enter was effective on stutters but now it has less effect on it.

Akatsuki Posted November 8, 2015 Share Posted November 8, 2015 I don't know if it helps, Cobra, but if i press the escape key the FPS becomes normal (i can see the PoV moving smoothly with TIR). returning to the game kills the FPS again. Link to comment Share on other sites More sharing options...
Teeter Posted November 8, 2015 Share Posted November 8, 2015 Best I can say is this: Pre-patch: 60 fps solid (w/ V-Sync) Post-patch: ~50 during startup, quickly decreases to as low as 20 once I start taxiing (quick start cold start mission). /Gregory Smiddy Programming Heatblur Simulations https://www.facebook.com/heatblur/ Link to comment Share on other sites More sharing options...

Pause the game, the fps will rise. Same in 1.5.0. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Teeter Posted November 8, 2015 Share Posted November 8, 2015 (edited) Pause the game, the fps will rise. Same in 1.5.0. Does this rule out a geometry/texture issue? To me, it does. Considering this, and adding my experience above (in which the fps drops linearly with taxi speed), I am willing to bet it is a FM issue. Perhaps the undercarriage?

mmaruda Posted November 8, 2015 Share Posted November 8, 2015 Just checked out of curiosity. It's playable for me, at least at free flight, but the FPS is far from solid and regularly drops with frequent stutters. This is with an i5 2500K@4,5GHz and a GTX 980 plus 16 gigs of RAM. I have a feeling this has something to do with the textures - not much stuff in the Mig that might cuase a drop (MFDs, mirrors), but the pit itself is definitely higher rez than other planes. Looks great, but I'd rather have more FPS. :( Link to comment Share on other sites More sharing options...

FeistyLemur Posted November 8, 2015 Share Posted November 8, 2015 I notice I have a large drop in FPS when I close my canopy. My trackir becomes super stuttery and hard to use. I have a cold start mission in krymsk i made with zero other planes or objects in the world and as soon as I closed my canopy I dropped to 50fps from above 60.

King_Hrothgar Posted November 8, 2015 Share Posted November 8, 2015 Similar issue here. My FPS according to nvidia is still around 60 to 120, but it's stuttering so badly that I doubt I'm actually getting more than 10. None of the other modules have this issue. The stuttering occurs in both cockpit and external views. System specs in my signature and all drivers are the latest version. I'm running at 1080p.

bart Posted November 8, 2015 Share Posted November 8, 2015 Same here...... I get 50 fps all the while, but as soon as I turn the battery switch on the stuttering starts but no drop in fps. Turn it off again and the stutter disappears.

Anatoli-Kagari9 Posted November 8, 2015 Share Posted November 8, 2015 But I wonder if there is at least a way around, because, no matter what I do, I am now getting that same alert message each time I start DCS :-/ Flight Simulation is the Virtual Materialization of a Dream...

theropod Posted November 8, 2015 Share Posted November 8, 2015 my fps is 80-110 at instant free flight mission, as you noticed there is no dense buildings and trees but feels like getting 30 fps like flying over forest areas. Link to comment Share on other sites More sharing options...
grunf Posted November 8, 2015 Share Posted November 8, 2015 I have 50fps at the start of the Cold start instant mission, going down to 25 during the taxi. It's much better after takeoff, 80-90. On an empty part of the map I have around 100fps. At least it says so, but due to the stutters it feels more like 20. :( With other modules at the same place I have 130fps, smooth, no stutter. i5 4460 3,2GHz , GTX970, 16GB RAM, SSD Link to comment Share on other sites More sharing options...
Cobra847 Posted November 8, 2015 Share Posted November 8, 2015 Investigation in progress. We have found that it is an intermittent spike in CPU load. This means general FPS is good (as it was before) - just this spike is making it feel like 20fps. Working on it.

The 21 is my favorite plane, I'd hate to have it grounded because of something as trivial as some CPU load spike.

Ok, so just for information: My FPS with other modules (mig 15, warthog) my FPS is at 70 consistently. With Mig 21 pos 1.5.1 my frames are in the 40's and I am getting the CPU spike you spoke of.
