Hey there, I'm using ENB 0.204 with several different presets. Most of them have ReduceMemoryUsage enabled.
I got a GTX 760 with 4gb of ram last week, so it should work, but it doesn't. I get huge stuttering with the option enabled, its butter smooth when I turn it to false.

Just a heads up, no hate. Keep doing your awesome work Boris!
Let me know if you need additional information, I do everything I can to help.

Updated to Version 0.206 getting the newest d3d9.dll and enbhost.exe
The problem is still there, if anything its gotten worse. As always, setting ReduceMemoryUsage to false fixes the stuttering.

Bug on your side, read my posts in downloads category of the forum. All you can do is to find what the problem and report it.
