TTW Performance Guide

Post by **Dead Sirious** » Thu Jun 25, 2015 2:10 am

Title says it all.

NOTE: Starting with TTW 3.0, many performance steps from this guide are already applied by the TTW installer. Follow these steps only if you're playing Fallout New Vegas without TTW.
If you're using TTW, you can still update your NVSE (if necessary), get NVAC, get NVTF and the Nvidia Profile Inspector if you want to.

NVSE is required. http://nvse.silverlock.org/

NVAC is required. http://www.nexusmods.com/newvegas/mods/53635

The newest 4GB patcher by Roy Batty and LuthienAnarion is required. http://www.nexusmods.com/newvegas/mods/62552

NOTE: TTW and the GOG.com FNV version already contain the 4GB Patch, so if you're using any of those, you can skip patching your FNV exe.

Nvidia Profile Inspector is highly recommended for Nvidia users. http://www.guru3d.com/files-details/nvi ... nload.html

1.) Search for Fallout New Vegas within the Profile Inspector. Set "Multi-display/mixed-GPU acceleration" to Single display performance mode. Finally set "Power Managment Mode" to Prefer maximum performance. Here's a visual example. http://i.imgur.com/6nYPWVX.png

2.) Search through Fallout.ini and FalloutPrefs.ini within your documents. Once there, set bUseThreadedAI=0 to 1. Once done, copy "iNumHWThreads=2," and paste it below bUseThreadedAI=1.

Repeat the same process for the Fallout_default.ini within your Steamapps\common\Fallout New Vegas folder. Here's a visual example. http://i.imgur.com/7rc6Gkq.png

3.) Now, we shall enable the engine's built in purging within the three INIs mentioned above. If you're playing with Zan's AutoPurge Crash Protector, uninstall it (you should uninstall it anyways) before applying these superior changes.

bPreemptivelyUnloadCells=0 to bPreemptivelyUnloadCells=1

bSelectivePurgeUnusedOnFastTravel=0 to bSelectivePurgeUnusedOnFastTravel=1

4.) Open the Data folder, and search for your NVSE folder. Once there, create a text file and name it "nvse_config.ini." Make sure to create it inside the NVSE folder, not the plugins folder. http://i.imgur.com/C1DLMyz.png

The value for DefaultHeapInitialAllocMB must be between 200 and 500. 420 seems to be the best value according to Roy Batty. It's recommended to play around with it and test the values yourself. ScrapHeapSizeMB is not used by the game so don't try adding that.

5.) Stop by the New Vegas Tick Fix page, download and install the most recent version.

https://www.nexusmods.com/newvegas/mods/66537 (NVTF)

6.) Open the Renderinfo.txt within your documents; Documents\My Games\FalloutNV. There will be a line for the Shader Package, 13 for example.

Now, go to the Shaders folder within your Data folder, and rename shaderpackage013.sdp to shaderpackage013.sdp_backup. Once done, make a copy of shaderpackage019.sdp, and rename it to shaderpackage013.sdp. Ignore the periods ending my sentences of course.

Do note, 13 is solely an example; the shader package depends on the number your Renderinfo.txt displays.

7.) Download http://www.nexusmods.com/newvegas/mods/61265 to improve audio performance.

There is an insert horizontal line button on the tool bar when creating a comment. Sixth button from the left.

Thanks for posting this.

I didn't notice before, but thanks for the direction! It's a lot more appealing for the eyes now. Hopefully, this saves the chat from having to deal with specific performance related questions daily.

Thanks for posting. Is there a tool to use if you're NOT running nVidia?

Post by **Dead Sirious** » Thu Jun 25, 2015 9:38 am

You're welcome! If there's no similar values within AMD Catalyst Control Center. Radeon Pro's probably your best bet.

For ATi users you need to create a new profile in CCC, there is a quide on the STEP project for doing this.

Just so I understand this correctly since I'm pretty clueless when it comes to video card stuff, whenever I want to run TTW I need to go into Inspector and select the FONV profile and when finished and I quit the inspector it will default back to the generic profile correct?

Post by **RoyBatty** » Thu Jun 25, 2015 9:47 pm

No, you have to add the exe's to the profile, then hit apply and exit Inspector and you never have to do it again until you update your drivers.

Oh ok got it..... Thanks...

Thanks for this guide!

I now have unistalled Zan Purge Mod and use the NVSE ini-file.

Does anyone have an idea how to reduce screentearing? I have a little horizontal line e.g. when moving the mouse up and down. With CCC and forced vsync it is better, but not gone. Are there any tweaks about this?
