FPS Drops Drastically for ERJ v.2 in Windows 8 (FS2004)

Recommended Posts



I know the low FPS issue has been frequently discussed on this and other forums. I too am experiencing this issue and, after researching it for several hours, have found that none of the solutions posted on this forum or others have worked for me.


I really enjoy the ERJ v.2 addon (which I'm running in FS2004) but this is what I experience:

FPS during startup/taxi: 50-60

FPS during takeoff/climb: 30-40

FPS during cruise: 10-20

FPS during landing: 5-10


As you can see, the addon works perfectly well at first but slowly, slowly starts dropping in performance until I can barely make a landing with such low frame rates.


I have tried the usual remedies: (1) lowering the guage refresh rates to bare minimums, (2) not using the VC for landing, (3) trying all kinds of variations on the compatibility mode settings (on/off for both FS9 and ERJ Config), (4) making sure my FS9 folder in Program Files has all security permissions "allowed." I don't have any addon airports installed and scenery and textures are default FS9. And I didn't install ERJ v.2 in compatibility mode. 


I have a relatively new gaming laptop and don't experience any low fps issues with any other addons (Carenado, A2A, etc.). Here are my specs:

Windows 8.0

Microsoft FS2004

Computer: Lenovo IdeaPad Y500 Gaming Laptop
Processor: Intel Core i7-3630QM 2.40 GHz
Graphics Card: NVIDIA GeForce GT 650M
Memory: 16.0 GB
I really like flying this aircraft but would like to fix this FPS issue so I can continue enjoying it! Please help... and thank you.

D. Scobie,


Thanks for the reply! I'm a little confused because in this post you said to install without compatibility mode. I'm willing to try it but just want to understand a little bit more about this fix.


Thanks again!

back in the early 80s IBM decided to outsource the OS and most of the hardware development for the PC.  this resulted in multiple builders and version of the OS.  now, many years later, different computers will work differently because of different OS, hardware and software interactions (Apple went the other way, except for a short period, and keeps everything 'in-house').


in general no compatibility mode works ... sometimes it does (see above).

Thanks for the reply. I reinstalled ERJ v.2 with compatibility mode (set to Windows 7). I did another flight, but, to my dismay, noticed the frames started dropping again after takeoff. Then I got the idea to try turning FS2004's default Real World Weather (Jeppsen) feature off. That instantly bounced the frame rates back up. I finished the rest of the flight with "Clear Skies" weather selected, and I had about 35-45 fps on landing (acceptable for me).


I'm not sure why I was not experiencing the same frame rate problems with FS2004 real world weather using Carenado and A2A addons. It may be that they run 10-20 FPS higher on average or maybe because my ERJ flights tend to be longer in duration. I'll do a few more flights to make sure the frame rates are stable under different conditions, but FS2004's real weather system seems to be the culprit here. Have you heard of this happening before?


I will soon install REX w/ Overdrive, which is known to improve FPS performance over default FS2004 weather. Hopefully this will make ERJ v.2 even more enjoyable! Thanks again for your help, D. Scobie, and I'll post on this thread if I have any more unusual FPS problems.

I'm actually still experiencing the frames problem. I don't think turning off the weather fixed it, as several other flights proved. I flew an offline flight with Clear Skies and still had the same FPS issues. Anything else I can try?


Thank you!
