Hi guys. So when I run FS9 on my desktop, I get good frames ( usually around 30+ fps), but if I install the ENB bloom effect, FS9 starts lagging, so I had to remove it. How can that issue be fixed?

This can't be really fixed, the better graphics put a strain on the system.

 

Try disabling the bloom effect in the enbini:

 

[EFFECT]
EnableBloom=0 <--- 1 is on

 

You will get nice colour tweaks but no fps-eating bloom.

 

Otherwise you need to adjust some other settings eg set AA to FXAA instead of a higher setting.

 

For an older game sim like FS9 FXAA gives good enough results.
