DXTory Lag

[schyler]

Every time I try to record BF4 I get only 40 FPS. What are the best settings for my system? i7-4790k, GTX 980 Ti, 24GB RAM ~140MB/S write speed. What advanced settings do I check? I tried Matrox and it lags even recording to a SSD, DXtory codec makes to big of files and Lagorith lags. I don't know how to setup vfw264
