Branimir 9 Posted February 21, 2020 Share Posted February 21, 2020 Hello!. When My CRJ Pro started to stutter a day ago. A have 15FPS in the cockpit with a very bad stuttering. It starts when I turn on the ground power (AC power, also happes with APU). When remaining four MFDs come alive my FPS drops from 30-40FPS to 15FPS with bad stuttering. This is the problem with MFD displays. If I disable FO side frame rate rises to 20FPS and if I also disable the captain side it rises to 30-40FPS. CRJ Pro was working completely fine few days ago. I had the same problem less than a month ago. I did a CRJ reinstall, P3D v4 reinstall and nothing helped. I bought a NVME SSD less months ago and I decided not to move (clone) the old SSD to NVME but to reinstall whole Windows 10 and P3D and start from the beginning because that should 100% fix the problem - and it did! But it was a pain to reinstall all addons, reconfigure whole system, P3D ... And now I have the same problem and complete Windows 10 reinstall is not an option for me because it is very time consuming to have the CRJ working properly for less than a month. All other planes are working perfectly. The problem also exists while in the outside view - frame rate is dropping to 15FPS and rising to 80FPS every second. I have just reinstalled my P3D and CRJ and I also deleted the .cfg file and there is no difference. It is also interesting that frame rate stays at 15FPS even if in move all settings sliders to full left position. The only thing I did before this problem started is installing an Air Manager Plugin that connects P3D and Air Manager software (home cockpit gauges for my C172 home cockpit project) together but I am sure that this should not cause this problem. I also reinstalled the plugin (deleting the .dll and removing an entry in dll.xml file) and it did't fix it. My PC specs: i7-7700 (HT enabled, running at 4.2GHz) 16GB DDR4 Gigabyte RTX 2070 SUPER GAMING OC Gigabyte 750W 80 Plus Gold Prepar3D V4.5 Hotfix 2 AS CRJ Pro 2.0.0.3 Do you know how to fix the problem because it is unflyable and I really want to continue flying this beautiful addon? Thank you! Link to comment Share on other sites More sharing options...
Branimir 9 Posted February 21, 2020 Author Share Posted February 21, 2020 I have also just found out that it works very randomly. After many restarts of P3D it worked and after another restart I am having the same problem. I have spent my entire day restarting and figuring out what is wrong and it worked fine on two occasions but I have this problem 99% of the time. I don't know what to do Link to comment Share on other sites More sharing options...

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted April 17, 2020 Aerosoft Share Posted April 17, 2020 We have looked at this issue from every possible side and simply have no idea what causes it. As we have three customers who see this issue and no other reports we have to conclude it is something specific on those three machines that is not on the thousands of others. But what that is? As said we simply have no idea. Sorry. Link to comment Share on other sites More sharing options...
KVAZEMODO 1 Posted April 18, 2020 Share Posted April 18, 2020 Hello. But there are many people who has a troubles with low FPS on great computers. All the reinstallation (Windows and so on) didn`t help. And It is sad. Will wait for the next update for the CRJ. Link to comment Share on other sites More sharing options...
vivaabc99 1 Posted May 12, 2020 Share Posted May 12, 2020 Also get this problem, any plane runs over 60FPS. AEROSOFT CRJ GOES UNDER 20FPS WHEN AC ON, REALLY FRUSTRUATING, I THINK IT HAS TO BE FIXED. There is no way the problem is on our machines, due to the fact that I run anyplane with over 60 FPS. Link to comment Share on other sites More sharing options...
Pineapple_Wizard 1 Posted May 12, 2020 Share Posted May 12, 2020 I've noticed something similar. I get massive fps fluctuations once the displays come on. I have a very strong PC and yet still it causes the FPS to dip down into 20fps and below. This also happened even on my old PC. I've tried tons of settings limiting and unlimiting fps to no avail. It seems there is something quite wrong. Link to comment Share on other sites More sharing options...

Developer Hans Hartmann 3695 Posted May 22, 2020 Developer Share Posted May 22, 2020 I still can't reproduce that. I have three PCs (i9-9900K/32 GB/RTX 2080ti, i7-5820K/32GB/GTX 1070, Notebook Ryzen 7-3750H/24GB/GTX1160. All with Windows 10 64-bit (1909, the i9 has 2004) and latest nvidia drivers) but I don't see any fps change on any of them. The only significant difference to you is that I use the latest almost-beta version of the CRJ Pro and not 2.0.0.3. Link to comment Share on other sites More sharing options...
KVAZEMODO 1 Posted July 1, 2020 Share Posted July 1, 2020 Last update didn`t fix a problem with low FPS. But i think, I found a reason of low FPS. It is not depends on AC ON, it`s connected with displays. So, when you push on the displays looks like on the picture, displays becomig dark. When displays are dark, FPS rises. Just try it.

Developer Hans Hartmann 3695 Posted July 1, 2020 Developer Share Posted July 1, 2020 Of course the displays have an impact on the framerate. Every additional display increases the number of drawing operations up to the point where rendering one frame takes longer than the time scheduled for each frame. The result of this is a dropping framerate. This is why I added the option to switch off the first officer displays. Removing those helps a lot.

CaptKornDog 41 Posted July 12, 2020 Share Posted July 12, 2020 Just installed the CRJ Pro, and I'm running into the same issue. This matches the behavior of the original CRJ but no other aircraft in my hangar. I ripped my hair out trying to isolate it on the original. For me, displays have no impact unfortunately. (i7 7700k @ 4.8, 1080 Ti with utilization only ~50-70%, Win 10 P3D v4.5 and default shaders; use ActiveSky & ChasePlane but disabling those has no effect.)

TKlemm 4 Posted July 14, 2020 Share Posted July 14, 2020 I'm having the same problem. Lots of stuttering in during ground movement. Other aircraft like the QW 787 with a lot of video displays and the QW RJ85 run smooth as silk using the same scenery and graphic settings. Is there a way to adjust the display refresh rate in the .cfg?

Developer Hans Hartmann 3695 Posted July 14, 2020 Developer Share Posted July 14, 2020 No, there's no configuration setting for this. After some experimenting I'm pretty sure now that the problem isn't related to the display refresh rate. Link to comment Share on other sites More sharing options...
canadagoose 9 Posted July 27, 2020 Share Posted July 27, 2020 +... This makes it what? 7, 8 out of 1000's with this problem. Come on Aerosoft! How about a little more quality customer support for all of us LOYAL Customers throughout the years (I'm Talking big $$$). We deserve a more positive support explanation and outcome than ..."As we have three customers who see this issue and no other reports we have to conclude it is something specific on those three machines"...Maybe the other 1000's of customers, who you claim must not experience this issue, just couldn't be bothered reporting it because they lack confidence that anything can or will be done about it. It is frankly, very frustrating and disappointing that the performance of this product is consistently poor during most stages of a flight in terms of FPS & stuttering. There, I got that off my chest. have a good one. Link to comment Share on other sites More sharing options...
Developer Hans Hartmann 3695 Posted July 27, 2020 Developer Share Posted July 27, 2020 I'm still working to figure out what exactly causes the problem. The fact that it doesn't occur here, doesn't make it easier. It is being worked on and there will be a solution eventually. Link to comment Share on other sites More sharing options...
canadagoose 9 Posted July 28, 2020 Share Posted July 28, 2020 Thank you Hans, that is encouraging news! Thanks for the reply. Link to comment Share on other sites More sharing options...
Branimir 9 Posted July 28, 2020 Author Share Posted July 28, 2020 i7-10700 (upgraded from i7-7700) fixed the isssue. Now there are almost no stutters and framerate is always between 40 and 60. Link to comment Share on other sites More sharing options...
NightOfDreams 1 Posted July 28, 2020 Share Posted July 28, 2020 My FPS temporarily drops shortly after takeoff, then goes back up. This is presumably because the sim is loading distant scenery. Most of my cores go up to 100% which coincides with the drop in FPS. Perhaps the CRJ is just that resource intensive that simultaneous sim functions overload the CPU, which causes the drop?
