First off, sorry for posting this here, but I've been able to get nothing at all from the Dxtory forums (they seem dead or broken)
Ok, so, I'm having an FPS issue when recording with Dxtory.
Normally, I can play pretty much any game at above 60 FPS, and the ones I have tested on are simple games like Don't Starve and Minecraft, which I can keep above 100 FPS.
But, when I start recording with Dxtory, my frames drop to about 45, in game, and 30 in the video.
These are my settings for Dxtory, and this is my PC
I've tried changing Dxtory settings around, as well as changing Lagarith record mode from RGB to YUY2 (which causes the framerate to stay at 60, but only audio is recorded, no video)
I've tried recording to my 2nd HDD (slower one), my main HDD (the one in the picture), and main SSD drive, and they all produce the same results.
I've already switched my AMD drivers to 13.12; on the newset drivers my FPS goes to about 12.
I'm really not sure what's going wrong here, as my PC should be powerful enough to do this.
