1. right click on dark souls in your steam library and go to properties
2. go to local files
3. go to data
4. right click on DarkSouls and click properties
5. go to compatibility and click on Run in compatibility mode
6. do step 4 and 5 for Data
7. click play

It should work

1. go to control panel and find the uninstall program section

2. uninstall microsoft games for windows - LIVE redistributable and microsoft games for windows marketplace

3. then go online and download GFWL installer

4. once downloaded [shouldnt take long] go to where its saved and right click on it and go to properties then compatibility mode and click run in compatibility mode and run as admin

5.r un the installer

6. once installed it should now work

DSfix has been known to cause major framerate issues

1. to fix any framerate issues once DSfix is installed go into DSfix.ini

1. and delete everything EXCEPT this

# Dinput dll chaining
# if you want to use another dinput8.dll wrapper together
# with DSfix, rename it (e.g. "dinputwrapper.dll") and put the new name here
dinput8dllWrapper none
# dscfix.dll

and anything else you wish to keep

my DSfix looks like this

# skip the intro logos
# this should now be slightly more stable, but should still be
# the first thing to disable in case you experience any problems

# Dinput dll chaining
# if you want to use another dinput8.dll wrapper together

Your DSfix when downloaded with no changes should look like this

# You can configure DSfix by editing this file
# Lines starting with "#" are ignored by the program and contain descriptions of the options

###############################################################################
# Graphics Options
###############################################################################

# internal rendering resolution of the game
# higher values will decrease performance
renderWidth 1920
renderHeight 1080

# The display width/height
# 0 means use the same resolution as renderWidth/Height
# (use for downscaling - if in doubt, leave at 0)
presentWidth 0
presentHeight 0

############# Anti Aliasing

# AA toggle and quality setting
# 0 = off (best performance, worst IQ)
# 1 = low
# 2 = medium
# 3 = high
# 4 = ultra (worst performance, best IQ)
aaQuality 0

# AA type
# either "SMAA" or "FXAA"
aaType SMAA

############# Ambient Occlusion

# Enable and set the strength of the SSAO effect (all 3 settings have the same performance impact!)
# 0 = off
# 1 = low
# 2 = medium
# 3 = high
ssaoStrength 0

# Set SSAO scale
# 1 = high quality (default)
# 2 = lower quality, lower impact on performance
# 3 = lowest quality, lowest impact on performance
ssaoScale 1

# Determine the type of AO used
# "VSSAO" = Volumetric SSAO (default, only option pre-1.9)
# "HBAO" = Horizon-Based Ambient Occlusion
# "SCAO" = VSSAO + HBAO
# "VSSAO2" = Volumetric SSAO with more samples (tweaked by Asmodean)
# VSSAO and HBAO types have a slightly different effect. and similar performance
# SCAO combines both, with a higher performance impact
# VSSAO2 is generally more accurate, but also requires more performance
ssaoType VSSAO

############# Depth of field

# Depth of Field resolution override, possible values:
# 0 = no change from default (DoF pyramid starts at 512x360)
# 540 = DoF pyramid starts at 960x540
# 810 = DoF pyramid starts at 1440x810
# 1080 = DoF pyramid starts at 1920x1080
# 2160 = DoF pyramid starts at 3840x2160
# higher values will decrease performance
# do NOT set this to the same value as your vertical rendering resolution!
dofOverrideResolution 540

# Depth of Field scaling override (NOT RECOMMENDED)
# 0 = DoF scaling enabled (default, recommended)
# 1 = DoF scaling disabled (sharper, worse performance, not as originally intended)
disableDofScaling 0

# Depth of field additional blur
# allows you to use high DoF resolutions and still get the originally intended effect
# suggested values:
# o (off) at default DoF resolution
# 0 or 1 at 540 DoF resolution
# 1 or 2 above that
# 3 or 4 at 2160 DoF resolution (if you're running a 680+)
dofBlurAmount 1

############# Framerate

# Enable variable framerate (up to 60)
# NOTE:
# - this requires in-memory modification of game code, and may get you banned from GFWL
# - there may be unintended side-effects in terms of gameplay
# - you need a very powerful system (especially CPU) in order to maintain 60 FPS
# - in some instances, collision detection may fail. Avoid sliding down ladders
# Use this at your own risk!
# 0 = no changes to game code
# 1 = unlock the frame rate
unlockFPS 0

# FPS limit, only used with unlocked framerate
# do not set this much higher than 60, this will lead to various issues with the engine
FPSlimit 60

# FPS threshold
# DSfix will dynamically disable AA if your framerate drops below this value
# and re-enable it once it has normalized (with a bit of hysteresis thresholding)
FPSthreshold 28

############# Filtering

# texture filtering override
# 0 = no change
# 1 = enable some bilinear filtering (use only if you need it!)
# 2 = full AF override (may degrade performance)
# if in doubt, leave this at 0
filteringOverride 0

your dinput dll chaining one wont has dscfix.dll it will have dsfix.dll

if dscfix is downloaded and is in the data folder then change dsfix.dll to dscfix.dll
