Struggling with FPS

Recommended Posts

Heya it's me again, this time with a performance related topic.

 

I've managed to complete a F&L install and everything seems working, though i'm still in goodspring so who knows what can happen next.

 

I know that retexture mods are very resource-eaters, but I thought that with my rig i should've handled them safely. I also know that AI-heavy places in game (such as goodsprings) are hard to handle, but still I couldn't imagine that they were SO hard to handle.  Anyway... Here's some info:

 

I don't run ENB (luckily at this point  ::P: ), just dynavision which I always loved

 

My rig is this: barebone notebook based on clevo HM170 model

 

CPU: i7 @2.40Hgz

Ram: 8GB DDR3

GPU: radeon 8970M 4GB (basically a 8950 for desktop, more or less)

the game is installed on a samsung EVO SSD

 

The problems start expecially in outside areas of goodsprings, where i get the amazing amount of 17/23 FPS (with AA set to 2 and aniso set to 8). Inside buildings it's ok, i get near 55/60 FPS and it's good. Outside town I also get ~45/50 FPS which is not a bad number at all.... I wonder though what happens if I reach another AI dense area, will FPS drop again to awful ~20?

 

I found a cool thread here where a guy had the same problems, but with a weaker GPU than mine. From that thread I managed to find a way to use shaders 3.0, which let me gain a good ~5 FPS raise in outside areas of goodspring. That's not bad at all, but I'm sure that there is a way to improve performance further.

 

For example, in that same thread I read that enabling multithreadedAI should not be harmful and could help improve things a bit.

 

So, are there more ways to raise my FPS, and where in falloutprefs.ini must I put the multithreadedAI=1 line?

Did you install the crossbow mod?  I hear that kills FPS in Goodsprings area, but I believe EssArrBee is aware of some FNVEdits that can fix that issue (if that's what your problem is).

Yes I have the crossbow mod, but i haven't it in the inventory... Does it matter? Didn't think about that though...

Yeah, I'm not sure about what triggers what (I forgot - it's been a while since I discussed this with EssArrBee).  Do a search for "crossbow" in F&L's main discussion forum to find the posts about it.  It's possible that this may be causing your FPS issues.

If you have the crossbow mod installed in any way shape or form, it will most likely dip your FPS by around 20 or so and cause massive stuttering; regardless of whether it's in your inventory or not. Though strangely enough, this doesn't happen to everyone. However, it is probably your number one issue at the moment. 

 

A few other tips/tricks for performance:

 

  1. Be careful about using Dynavision's dynamic depth of field. I don't know about others, but for me it destroys performance.
  2. Try turning full scene water reflections off. That has caused me performance issues even in areas without water. 
  3. Remove the grass and lighting tweaks that EssArrBee recommends in his guide. He says they don't impact performance much if at all, but I swear they cause my game to stutter even more than usual.
  4. Turn off the games V-Sync and turn off the Stutter Remover's FPS management function. Then, go into your graphics cards control panel and force Adaptive V-sync for New Vegas and the 4GB launcher (this one is huge for me).

I hope these help you some.

Thank you, I'll surely try out that, besides adaptive vsync which is not present in amd cards IIRC. Can't find it in my video control parent

Ah. I didn't realize that AMD did not have an Adaptive V-Sync equivalent. Which is a shame because I use it ALL the time. Still, I would force your card to enable standard V-Sync over the games version of V-Sync. Or maybe it is fine for you, but for me it is extremely choppy and causes me stutters. But if it is fine for you I suppose then don't worry about it. :)

Should I also force AA and Anisotropic filters? Right now I have AA off and aniso at 8. Since I don't use any ENB or ENBoost, i could try using adaptive AA which maybe is less taxing than pure multisampling AA..

 

edit: apparently adaptive AA could cause problems, I found a skyrim thread where it is stated that some textures become invisible with Adaptive is on, unless relative meshes are extracted. Nvm...

 

Regarding Vsync, should I activate also triple buffering?

I would let the game hand AA and AF. Triple Buffering I think is more of a preference than anything else. I use it personally because it removes some of the input lag caused by V-Sync. I suggest you turn it on and play without for a while, and then turn it off if you notice any issues.

      Step Fallout: New Vegas Guide 1.0.0 released!

      Guide Link | Changelog | Feedback & Bug Reports
      Nexus Link
      Many thanks to @Majorman for working on this guide for the past 6 weeks as our official FNV guide Curator!

      This is a beta of [FNV|FO3|FO4|FO4VR|TES5|SSE|TES5VR|ENDERAL|ENDERALSE]LODGen/Edit with terrain LOD meshes and textures generation.
      This is for experienced mod authors and users that know how to use xEdit, xLODGen or DynDOLOD already.
      Installation and Setup
      Download
      xLODGen beta 86 - based on 4.1.4b
      Unzip into a dedicated folder outside of any Steam, game or mod manager folders or special Windows folders like Program Files.
      Rename xLODGen.exe to [game mode]LODGen.exe (TES5LODGen.exe for example) or start with command line parameter -fnv, -fo3, -fo4, -fo4vr, -tes5, tes5vr, -sse, -enderal, -enderalse
      Use -o:"c:\OutputPath\" command line parameter to change where files are generated to, default is the game folder.
      Do not generate into any game or any mod manager folders.
      Requirements
      Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 - Required by LODGen.exe/LODGenx64.exe and Texconv.exe/Texconvx64.exe. Get matching platform x86/x64 depending on which xLODGen.exe (x86) or xLODGenx64.exe (x64) is used.
      RTFM and Share Results
      See the included Skyrim-Occlusion-Readme.txt for a brief explanation of the Skyrim TVDT Occlusion data generation. Read the hints that are shown when the mouse pointer rests on a setting. Ask specific questions or give feedback in the dedicated Skyrim TVDT - Occlusion Data thread.
      See the included Terrain-LOD-Readme.txt for a brief explanation of the settings for terrain LOD generation. Read the hints that are shown when the mouse pointer rests on a setting. Ask specific questions about terrain LOD in this thread for a more in-depth explanation if required and share feedback (with screenshots) about results or problems.
      These tools generate LOD meshes and textures "exactly" like CK, but not like the meshes and textures which are shipping with the games (they are often manually edited).
      However, these tools provide more options and higher resolutions (use the x64 version if there are memory errors because you believe you require 4k or higher) and can be updated to add more useful features and options.
      I did some testing in the different games, but finding the best combinations of options and settings requires lots of testing and are a matter of personal opinion and which game is used, the load order, mods, even different worldspaces probably.
      That means, I am only able to give generic guidelines and hints to send you off to find and test for yourself and share your results. My main interested is that generations works correctly and without problems for now.
      Check out the thread xLODGen Terrain Settings Compare. Also refer to any modding guide which has a list of relevant mods close to your load order.
      The object and tree LOD generation is the same as the current versions of xEdit / xLODGen. Refer to their respective descriptions and explanations.
      Obviously, users of Skryim/Enderal/Skyrim SE/Skyrim VR/EnderalSE continue to use the easier and more comprehensive DynDOLOD for drastically improved object and tree LOD generation and only use xLODGen for terrain LOD (and maybe Occlusion) generation.
      First Time
      Here are suggestion to start without going crazy and that should be quick enough to generate:
      Set quality of meshes for LOD4 to 5 and then +5 for each next level. Or just set levels 8/16/32 to 10.
      Check protect cell borders (yes it fixes the ugly terrain drops at outer cell borders that still exist in Fallout 4).
      Use the max vertices setting only if you want to hard limit max file size.
      In Skyrim Special Edition or Skyrim VR, if you notice terrain briefly flickering when new areas are loading in, set [Display] bEnableLandFade=0 in Skyrim.INI
      Set Optimize Unseen to off for LOD4 for first generation. Start experimenting with a value of 550 with a quality setting of 10 or lower for LOD32 (used for map) and compare coastlines and file size to other settings.
      To quickly generate terrain LOD meshes just for the map, check only terrain LOD Meshes, check the Specific Chunk checkbox and set drop down to 32. Leave SW fields empty for complete map or set SW cell coordinates to same values as a *.btr filename to test a specific area with lots of water, river etc.
      Set texture sizes to 512 for a start. Larger sizes and large world spaces will take a considerable time (like 15 to 30 minutes or more easily). Each higher resolution means quadruple the work.
      Use DXT1 for diffuse and 565 (DXT1 if on Windows 7) for normal maps. If generating for Skyrim Special Edition use BC7. Uncheck mipmaps, raise steepness and Bake normal maps.
      For now, leave the Brightness, Contrast and Gamma at 0 and 1.0 respectively. It seems that only Skyrim CK and Skyrim SE CK are manipulating the intensity of the textures to adjust for the noise.dds and the god awful "improved" snow shader of Skyrim SE (just turn that thing off, really). If textures seem too dark in the game, brighten the noise.dds instead or vice versa. That way you can get perfectly matching LOD textures that look just like the textures in the loaded cells. For Skyrim a good average color of the noise texture seems to be around #C0. See below for a couple noise texture downloads.
      If you want to test larger texture sizes, use the chunk option to limit the number of textures that need to be generated. For example, check [x] Specific chunk, leave the drop down empty and set WS to the lower left cell coordinate of an 32x32 area, like 0, 0. It will then generate all textures up to 31,31. Not all worldspaces have their origin at 0,0 so you will have to check already generated meshes/texture filenames for their lower left coordinates.
      Questions and Feedback
      Obliviously anything related to terrain LOD should be posted in this thread.
      Posts related to Occlusion should be made here.
      Recommended Optionals
      TES5-Terrain-Tamriel.esm (Mega), SSE-Terrain-Tamriel.esm (Mega)
      TES5-Terrain-Tamriel-Extend.esm (Mega), SSE-Terrain-Tamriel-Extend.esm (Mega) - These extend the sea of ghost further to the north (see screenshots)
      SSE-Terrain-Tamriel-Full-Extend.esm (Mega) - Entire map from -96,-96 to 95,96 with northern ocean extension. Useful for mod authors.
      Put in game data folder obviously. Adds back terrain for Skyrim (Tamriel worldspace) at the outer edges so there is no missing terrain meshes/textures when generating terrain LOD for Skyrim.
      Load as early with lowest priority as possible, so that any other plugins overwriting or adding land records or cells with the same coordinates take precedence.
      Only required to be loaded when generating terrain LOD. No harm done when loaded in-game but typically the player can not get close to these areas. There are no effects outside the far away added cells.
      Noise
      Single color flat noise, Adjusted vanilla noise, HD Terrain Noise Texture SE
      Examples for Skyrim. Install to game folder like any other texture mod. The noise texture is applied in-game on top of terrain LOD textures, so no effect for LOD generation.
      Only the red channel is used in case the textures is not a grey channel format. MipMaps are ignored. The textures is tiled 3x3 per LOD quad, e.g. for LOD level 4, the noise texture is repeated 3 times to cover 4 cells, for LOD level 8, the noise texture is repeated 3 times to cover 8 cells and so on.
      Test-Terrain-Tamriel.7z
      For testing terrain LOD distances. Plain color terrain LOD textures for Tamriel with coordinates for every LOD quad. Green for LOD 4, yellow for LOD8, blue for LOD 16 and red for LOD 32.
