Number of errors after fresh install

Hi
I have been getting the following errors in assetto corsa after installing reshade with all of the effects:

warning: X3206: implicit truncation of vectory type
I get this one for a number of effects installed

error X4566: offset texture instructions must take offset which can resolve to integer literal in the range -8 to 7
this one i get for grainspeed.fx

I haven't changed anything in my setup, everything is default.

What can cause these issues? 
Plus question: I have a gtx 1070 and I've been experiencing some strange fps drops after installing reshade. I know it's a gpu demanding extension, but I see people with less powerful gpus having way more fps with the same game and preset. Am I doing something wrong or what? thank you

Warnings aren't errors, the shaders returning them will still compile and run. The actual error is probably being thrown because of a difference in how ReShade 5 and ReShade 4 handle tex2Doffset calls - the shader might need to be updated to be compatible with ReShade 5.

An abnormally low framerate against a comparable GPU configuration could be caused by vertical sync being enabled, and failing that, is usually caused by the CPU being unable to process frame pre-renders as quickly as the GPU could use them (to check if this is the case, use MSI Afterburner's overlay to monitor your GPU usage % ingame - if it isn't reaching 100%, you have a CPU bottleneck). If this is the case, either your CPU is too old, or there's too much background activity happening.

I wouldn't think that the problem is the cpu because it's a 9700k. With vsync off it's a lot better, but then the game is quite unenjoyable. Image is falling apart. This might be the only solution? to turn off vsync?
