Well done! Those are the same sections I'm using for AW/Optimus, meaning that nv_dispi.inf is not required. I'll be adding these entries for the next release, just copy nvcvi.inf from Clevo PEG and ditch nv_dispi.inf instead. %NVIDIA_DEV.13D7.7102.1558% = Section064, PCI\VEN_10DE&DEV_13D7&SUBSYS_71021558 %NVIDIA_DEV.13D8.7102.1558% = Section064, PCI\VEN_10DE&DEV_13D8&SUBSYS_71021558 %NVIDIA_DEV.1617.7102.1558% = Section064, PCI\VEN_10DE&DEV_1617&SUBSYS_71021558 %NVIDIA_DEV.1618.7102.1558% = Section064, PCI\VEN_10DE&DEV_1618&SUBSYS_71021558 %NVIDIA_DEV.13D7.7102.1558% = Section063, PCI\VEN_10DE&DEV_13D7&SUBSYS_71021558 %NVIDIA_DEV.13D8.7102.1558% = Section063, PCI\VEN_10DE&DEV_13D8&SUBSYS_71021558 %NVIDIA_DEV.1617.7102.1558% = Section063, PCI\VEN_10DE&DEV_1617&SUBSYS_71021558 %NVIDIA_DEV.1618.7102.1558% = Section063, PCI\VEN_10DE&DEV_1618&SUBSYS_71021558 NVIDIA_DEV.13D7.7102.1558 = "NVIDIA GeForce GTX 980M" NVIDIA_DEV.13D8.7102.1558 = "NVIDIA GeForce GTX 970M" NVIDIA_DEV.1617.7102.1558 = "NVIDIA GeForce GTX 980M" NVIDIA_DEV.1618.7102.1558 = "NVIDIA GeForce GTX 970M" nvcvi.inf_v378.78_Win10_P170EM_980M_970M.zip

Latest driver 378.78, same thing for GTX 970m, installs with this infs runs dx11 no dx12 or vulkan. Suposedly laptopvideo2go inf mods work with clevo optimus + 980m or at least i dont see any complaints from those users, but not for gtx 970m which installs but optimus never kicks in. With this ones performance seems equivalent or slightly better then previous on dx11. This doesn't sound promising tbh, there is little point in installing drivers which optimize dx12 if u cant actually run dx12 There are at least a couple more users in same situation as me in Clevo subforum so it is definitly not an isolated issue. Also It really seems like not a driver compatibility problem because J95 infs do work to some extent which means something for sure can be done to fix this at inf level. So far I have heard from no other gtx 970m users who actually managed to install new drivers in this kind of setup, so im presuming they are just sticking to old versions. If anyone has any idea on how to get this working please share.... Anything goes at this point. SOLVED(for current driver) clevo p170em+gtx970em: Ok so after weeks looking in foruns and crap i managed to find a combo that worked.... Here is how i got it working 5m ago: I only needed to mod 2 inf files, nvcvi.inf and nvdispi.inf. I started by the original nvcvi.inf and looked for my device 13d8 which already existed, there was no reference to my latpop/model on the one provided in this forum or anywhere online so far. So I basically added the ids (7102 for my p170em) on top of the code for another clevo laptop wich connects to section063. I'm not sure if I changed anything else, but in the section I did import the code for that part from J95's inf. As far as I remember thats all the mods i did. Saved and decided to use the nvdispi that so far got me optimus support as base(j95s), no changes. Tbh I had little hopes of this working since I have used guides in past to mod infs and they all failed miserably. Somehow this time not only installed perfectly(no need to delete folders or whatever) it also enabled dx12 and vulkan support with optimus something I havent experience ever since I upgraded this laptop. I will upload the working inf files for whoever needs. Not sure they'd work for future drivers though. meanwhile... ALELUIA! p170em_gtx_970m_378.78.zip
