How to counter fps drops/freezes?

[Myrthian]

I'm using the 4GB patch, and despite only running NMC + flora overhaul as graphic mods I get frequent fps drops from 60 down to 35 or less, even indoors.

 

Outside it even leads to complete freezes for 2-3 seconds.

 

Anything to counter that?

Stuttering or "micro-stutters". All visual stuttering problems are caused by the video stream having to wait for the "art assets" required to render the display OR the game writing something to disk (such as a save game file or logging). Mostly these are due to the hard disk drive being orders of magnitude slower than VRAM, with System RAM (e.g. "ENBoost") and "solid state drives" (SSDs) being in between. Keep in mind that this game was designed for older PC and XBox console systems, and it is now possible for your new "latest and greatest" gaming machine to be faster than it can handle. There are internal design choices that cannot be overcome. The "video pipeline" has always been prone to problems. The following are "mitigations" that have been found to help some people.

Please see the following entries under the 'Solutions to Performance problems' section in the wiki Fallout NV Mod Conflict Troubleshooting" guide if you haven't already.
* 'Issue: "Full screen mode" exhibits CTDs and stutters or micro-stutters'
* 'Issue: Lag or "micro stutters" even with "New Vegas Stutter Remover" installed'
* 'Issue: Win10 Screen tearing in "Borderless Windowed Mode"'
* 'Issue: CTD without warning, "Out of Memory error", or stops responding after the Main Menu' for other settings that can indirectly affect micro-stutter.
* There are also some NVSR configuration suggestions under the 'Issue: Game in slow motion' and entries. (These will not help with the "Tick Fix" alternative mod, but the author of NVSR now has a suggested configuration for Win10 linked there.)
* The 'Issue: What's with these Solid Green billboard signs in the distance (LOD)?' entry under the 'Solutions to Mesh (Red "!" icon) or Texture (solid color) problems' section can also help if your problems started after you installed VWD/LOD texture packages.
* If you are using CASM or some similar "auto-save" mod to manage your save game files (recommended), try increasing the "time between saves" set in the "save frequency"; and reducing the number of occasions it saves to the minimum (e.g. disable most "Autosave Events" in CASM) and see how that impacts the game seeming to freeze temporarily.
* If you have "NVSE logging" enabled (see the 'Checklist Item #4' entry in the wiki "Fallout NV Mod Conflict Troubleshooting" guide), disable it until actually needed.
(Reading from or writing to disk for any reason is the slowest thing the game does.)

The size of your image files also has an impact. Larger/higher resolution is not always "better". Please see the wiki "Display resolution versus Image Size" article.

The 'Issue: What INI edits seem to be most beneficial to performance' entry of the wiki "Fallout NV Mod Conflict Troubleshooting" guide) may also be some help. However, the above mitigations are more likely to have a fundamental beneficial effect with or without any INI adjustments, so consider them as the last resort.

As you can see, there are a number of things that can underlie your problem. If one of these doesn't fix it, I would be interested to hear about any eventual solution that does.

Thanks.

 

I did try the windowed version, but didn't really like it.

 

So far I've only had a few fps drops, but no stutters, over several hours, using: https://www.nexusmods.com/newvegas/mods/66537?tab=description
