Having done a few hours' research, the potential 'solutions' are all over the damned place and I'm not quite sure what's up. I've heard differing reports on the success of using Crossfire on New Vegas, and I'm looking to get a range of opinions. However, before I go throwing my money at anything, I want to check that this will actually work. This, I understand, lends very good performance numbers across the board - generally equivalent to the high-range R9 290X graphics cards, which generally range for about $500, depending on manufacturer. The alternative is adding on a second R9 270X graphics card, as I future-proofed my motherboard by purchasing a Crossfire-compatible one. However, looking at the situation, I'm unlikely to see any sort of significant performance increase unless I'm willing to spend in excess of $400 on a graphics card, which I'm frankly not. My understanding of ENB is that it's pretty much a graphics card-only application, and that if I want to improve my situation, I'd be best off improving my graphics card first and foremost.

The primary issue, moreover, seems to be ENB - the game runs at a pretty neat 45-50 FPS if I disable it by removing d3d9.dll from my FNV folder. I use some pretty hefty texture packs for armour (Book of Steel), as well as WRP, but I only run the 512x512 NMC pack, which is the same resolution as vanilla. My mod setup isn't nightmarish - the only two real performance killers are the additional NPC mods I use (since the whole game just feels horribly under-inhabited without them), and my ENB. Now, my current rig is an i5 4440 CPU, 8GB of RAM and an R9 270X graphics card. So I'm looking to improve it - preferably up to the 45-60 mark, which seems to be the upper limit on the TV that my gaming PC is hooked up to. Running the specs I have, I tend to be seeing some pretty minimal performance (a round 30 FPS average), which drops significantly (to around 15-20 FPS) whenever I'm looking at a large number of NPCs (oddly, the drop doesn't happen when I'm not looking at them). So, I'm in the process of thinking about updating my gaming rig. Mods, feel free to move it about at your whims!) (Unsure if this is the right forum for this thread - couldn't figure out whether to put it here or in the Technical Support forum.
