OpenCL 1.2 seems to be workable with newer versions of SMP, have tested with NVIDIA 1080ti with encouraging results.OpenCL 2.0 was a requirement for HDT-SMP, while there is an option to turn off OpenCL simulation in the configs.xml the engine will crash without it, this option actually just sets SMP to use CPU rather than GPU calculation.Nvidia, try these these will only work if you have compatable Intel CPU.If you are on Windows 10 and have an Intel CPU/GPU you probably can ignore this.If the above configuration works and you have physics enabled, you are good to continue if not then you may need to check if your hardware is compatible with SMP's requirements. Install Bodyslide if you are testing with a body mod, make sure to build the Physics or SMP version of the body Install one mod that uses SMP to test with (bodies are good for this, e.g. Install XP32 Maximum Skeleton (might not be required if your mod comes with a physics skeleton) Install HDT SMP manually, i.e not with your mod organizing tool Install SKSE manually, i.e not with your mod organizing tool Use a mod organizing tool (Mod Organizer is my recommendation)

If this is the first time you are trying SMP I would highly recommend doing the following benchmark first before going any further. If everything works as desired after installing any of the SMP bodies then there is no need to read any further. Special Edition - Install either of CBBE or BHUNP they should be all you need to get clothing and body physics for most mods. Legendary Edition - Just install BHUNP, this should get body and clothing physics for most mods SMP is based on Bullet and can handle much higher force without breaking. SMP solves a lot of the issues that PE had, spazzing mesh, inaccurate collisions etc. What is HDT-Skinned Mesh Physics?, essentially it's a better version of HDT-Physics Extension originally developed by the lovely HydrogensaysHDT (open source now). Disclaimer: Some of these links are to LoversLab, I apologize if this offends anyone but most of the resources for SMP are only available there.
