After installing FSDreamteams's CYVR airport scenery, I'm experiencing a screen freeze for about 25 seconds when starting a flight anywhere near CYVR - even starting at Vancouver Harbor aerodrome 7 nm away. I also get about a 5 second freeze when I get close to the runway on approach. I get acceptable performance for FSX:SE for the most part just about anywhere else (including flying over ORBX EU-Wales terrain), but I really struggle for frame rates around Vancouver CA.

I also have Ultimate Terrain X Canada installed. Prior to installing FSDT CYVR I was only getting a mid-high 20 fps around Vancouver, but not the dismal high teens I now occasionally experience post CYVR install. I've already disabled many frame robbing settings in UTX and I chose all minimums on the FSDT CYVR install. So I don't think I can do much for further tweaking either. I'd prefer not to use UTX Canada as my impression is that it's poorly optimized for the city of Vancouver, but unfortunately I need it to support aerodrome addons for my province; important to me as I'm a fan of seaplanes and bush piloting. I also have the FS Global 2010 mesh installed.

FSDT CYVR requires the GSX 1 & 2 trial to be installed, which is an addon I wasn't familiar with. I wondered if it might be part of the cause, but I've tried taking off from SFO where the GSX trials are supposed to also work, and got acceptable performance. It's funny because with the demo of FSDT CYVR I didn't experience these freezes.

I don't have a powerful PC; i5 2500 4 x 4.33 Ghz, Sandy Bridge mobo, 16 GB DDR 3 RAM, Geforce 1660 w/6 GB DDR5. I get much better frame rates in X-Plane 11 for the same airport and vicinity even with details set to high though, so such poor performance in FSX doesn't seem right. I have another thread in the DX10 forum about settings that aren't enabled in my FSX.CFG file. So if anyone thinks this might be related to missing config file optimizations, I'd appreciate if you could take a look at that thread too.

Any ideas or suggestions as to what might cause this, would be much appreciated.

Well looks like I partially fixed my problem - the dreaded Ground_Shadows=1 was set in my FSX.CFG. Darn it, I could have sworn that was disabled! I still get the temporary 25 second freeze on flight start near CYVR, but everything after that is now running much smoother.

Nevermind; I found this thread at the FSDreamteam CYVR forum and the FSDT reps response describes what's likely going on in FSX:SE for me. So despite my having multiple CPU cores, the CYVR scenery addon can't make use of them when loading.

Wow that it's still a problem using the scenery in Prepar3D v4, which is now 64 bit. Makes me very glad I didn't fork out the $200 for that sim.
