This might be related to vsync or the frame limiter in your enb. For me I have to disable the frame limiter and vsync in my enblocal and use nvidia inspector to set a frame limit and set the Vertical Sync Tear Control to Adaptive. I also set the Vertical Sync setting to force off. The above settings work differently for everyone but it is another place to try different settings to see what help you config. In my testing I also noticed the enb vsync with frame limiter directly effects my script latency. When I have the convenient horses script latency running I get an average of 70s with the enb frame limiter enabled and 35s with it disabled. I don't get this issue when using nvidia's frame limiter.
