After I've installed shaders and started Minecraft I discovered one thing:When I set render distance to tiny in OptiFine my GPU is about 40% loaded, but on Extreme load is less than 10%. So FPS gets from ~50-60 on Far to about 20 on Extreme. Java assigned to use discrete GPU and updated to last version. No bottlenecking (CPU is from ~70 to 40% loaded) or Intel HD Grafics driver discovered. Also have more than enough RAM assigned. After a day of searching the net I haven't found a solution. How can it be fixed?
PC specs
Core I5 4460
GTX 970
8Gb RAM
Win10
Thanks!
And also sorry for my English if something is wrong.
 
@Alexandr_sym you need to install nvidia drivers.
Intel ones will not be used when a dedicated graphics card is used
did you allocate 4GB of ram in the FTB Launcher settings?

I have them installed. As I said my only working GPU is GTX 970. Also monitor is plugged directly into it. And yes, I have 4,5 GB RAM allocated.
 
okay.... so it is probably something in the minecraft world or log that is lagging up the place.

If it can help I can send some screenshots of tests when I get home (probably about one or two hours).
 
hmm I dont see anything abnormal... but from my understanding shaders also use a lot of cpu to do all the fancy stuff. Do you have the fps capped at Vsync?
