Update on the situation : Ralf (Vorpx maker) fixed the issue for me I am now using his temporary fix until the fix makes it into his next update.I immediately regained all my fps when using MO. He doesn't want that temporary fix to be known right now, but basically it seems that MO, when launching Skyrim, messes with the DLL search paths (on my machine at least, probably not everyone) and stops Windows from finding that "vital" system DLL.Thus making Vorpx unable to find my Windows version and to launch itself into the right Grab mode, resulting in huge loss of frames.

I’ve been checking lots of logs from MO or SKSE but found nothing. I checked vorpx logs this time, and found differences when launching between skse only and when launching through MO. Basically, I did find error lines (and other additional lines) from the log when using MO, that aren’t there otherwise if I don’t use MO to launch SKSE : ERR: _IsWindowsVersionOrGreater Error: GetFileVersionInfo failed. ERR: MultiMonitorGetConfig not supported in OS < Windows7 ERR: _IsWindowsVersionOrGreater Error: GetFileVersionInfo failed. INF: D3D9 BufferGrabber initialized. Grab mode: 0 (when I don’t use MO it says Grab Mode: 1) INF: SettingsUI: Init (this is the end line, it doesn’t appear when not launching through MO). Vorpx maker did reply this : "If the mod manger forces vorpX into grab mode 0, which is indeed slower, the solution to your issue is not using the mod manager. I will take a look at it, but since this likely is some odd modification to your system config caused by the mod manager, I can’t promise that there will be any other solution than not using it.Judging from the errors in the logfile the mod manager seems to enforce Windows reporting a wrong version number for whatever reason.You could check whether you accidentally did set Windows XP/98 compatibilty mode for it. If you didn´t, apparently it does something similar on it´s own" This is devastating news to be honest, because any mod manager that isn’t MO, is, to my frank opinion, pure garbage and should never be considered.From what I’ve read in their forum Nexus Mod Manager is barely working if at all since the new version… Is MO the only manager that can keep the vanilla files intact and who don't have new mods overwrite older mods which is a nightmare?

I am not knowledgeable enough to explain the functioning.It converts the displayed image into a suitable stereoscopic 3D image inside the oculus rift. Basically, right now, the situation is that launching skse or the launcher normally will give me around 50 to 60 fps inside the rift.But launching the skse or launcher through MO (once again, we are talking about a vanilla MO with the same INI files) will give me 30 to 40, which isn't playable in virtual reality. And as I said, benchmarks have shown that the drop in frame-rate only occurs inside the rift.So it is an issue between MO and Vorxp (or Oculus drivers). I thought that knowing this would help me fix it but after again many hours of no results I am getting desperate.The only little thing I can find is that it seems that when using MO and Vorpx, the GPU usage is around 8% lower.But CPU remains the same.But 8% shouldn't explain such a huge difference in frames.

Oh well, I feel stupid because the very last thing I expected was a conflict with Vorpx (because nobody has ever had this problem when checking Ralf's forum). I was doing my benchmarks inside my CV1. I just ran 2 benchmarks without the oculus rift, on a 1080p screen (needed to boost ugrid to maximum and settings too because it's hard as hell to go below 60 on a 980ti with a vanilla game), and Skyrim Performance Monitor reported the exact same numbers between a game launched normally and launched through mod organizer. So now it all comes down to why Vorpx Skyrim runs slower when launching through Mod Organizer.Sorry for the trouble, I will ask for Vorpx's maker directly, but still if anyone here has an idea I would be interested in it.

It cannot be a INI issue, I always modify the mod organizer ones and automatically copy paste them to my games/skyrim for my benchmarks. I am going to check this BethINI program, thanks for the recommendation. Well, as I said, I did clean drivers installation already.I can do it again I guess and report. I am still trying to see if it an external program that causes the issue.Are there any program that could help monitor the background processes behaviours while in game? I saw a program once that said could disable useless backgrounds when in Skyrim, what is it called again?

Thank you for your reply.It isn't a steam overlay issue. My benchmarks have shown similar GPU usage with or without Mod Organizer.Actually, running with Mod Organizer did show a GPU usage around 5% lower but I do not consider this difference to be significant enough, as it wouldn't cause a loss of 20 to 30 fps in average (the CPU did run at the same speed).Thus I do not think it is Nvidia software related, even though I do believe Mod Organizer has to be conflicting with an other program somehow.

Hello.I have a similar issue. After 3 months without playing the game I tried to finish the modding I started and immediately noticed a 20 to 30 fps decrease on my regular test path from Riverwood to Whiterun with a blank save (I am a CV1/Vorpx, I take FPS Very seriously). I immediately suspected an hardware issue but after enough benchmarks and clean driver installations I was able to tell it wasn't it (I have an 980TI and 4790K), nor was it a setting issue on the control panel. Launching the game through MOD Organizer with every mods unchecked didn't improve the frame-rate, so I assumed my game was broken. After a clean installation of everything (the game, mod organizer etc) I launched the game via the normal launcher as a quick test with settings similar to what I used before (I play in virtual reality so I didn't use anything that would lower my FPS to begin with) and I had my old Frame-rate back. But then I was in for a huge surprise when I installed MOD Organizer and SKSE, launched the game and saw, once again, a 20 to 25 FPS decrease on a totally vanilla MOD Organizer (no lag spikes at all, only the framerate is impacted). I suspected SKSE this time, but no, SKSE wasn't the culprit when launched alone. And finally, after all my troubles I started to suspect MOD Organizer itself, the one and only thing I would never incriminate because it can't lower the FPS. Tests did confirm it was indeed MOD Organizer that was lowering the FPS. It has now been 10 days that I am taking absolutely all my free time to try and fix it and sadly, for the first time, I have absolutely run out of ideas. I do not run any program supposed to improve FPS/etc in the background and obviously I am aware of simple things such as ini locations/user permissions etc. I welcome any idea really as to what is going on.Lately I have come to the conclusion that some program has to interfere somehow but I just can't find any issue at all on what is running on my computer.
