Would the game be reading and writing to the hardrive during game play unless you don't have enough ram to run it and windows without it using virtual memory?
I can see a SSD helping with load times but if you have enough ram I can't see how it helps during game play. The only exception I can think of would be if replays are being written to the hard drive during actual driving .
Was having terrible stuttering with obs. My resources were fine so there was something else at fault. This fix worked like a charm.Try this:
Open the graphics.ini and change MAXIMUM_FRAME_LATENCY from 0 to 1
[DX11]
MAXIMUM_FRAME_LATENCY=1
MIP_LOD_BIAS=0 ; GO NEGATIVE (ie. -1) TO SHARP THE IMAGE
SHADOW_MAP_BIAS_0=0.000002
SHADOW_MAP_BIAS_1=0.000015
SHADOW_MAP_BIAS_2=0.0003
ALLOW_UNSUPPORTED_DX10=0 ; UNSUPPORTED USE AT YOUR OWN RISK
SKYBOX_REFLECTION_GAIN=3.0
graphics.ini location is (by default instalation of Steam ):
C:/Program Files/Steam/steamapps/common/assettocorsa/system/cfg/graphics.ini
