Visuals & Graphics Remastered ReShade (and possibly modpack too)

How do I remove the previous reshade that I have

Delete "reshade-shaders" folder will remove all old shaders. Delete "DefaultPreset.ini", this will remove settings for shaders you just removed. Now use Colbydash's installation guide, this will update the dll(s) and add a clean settings ini ("DefaultPreset.ini"). Once you have Colbydash's zip file properly extracted, play the game. While at the menu, hit your "Home" key (keyboard) to bring up Reshade menu. At the top, you see tabs Home, Settings, etc. Click Home. Just under the tabs you will see a preset with arrows left and right. Click an arrow until you see Colbydash's "Simple_Remaster" preset. At the bottom of Reshade menu, find "Performance Mode", put a check in the box. Hit "Home" or "ESC" key to close Reshade menu. Play game.
It's Coldybash's modpack. If you want him to include your mods in his pack just talk to him but please don't release mods in his thread. You can also create a thread and release your mod/s if you want.
