Guild Wars 2

So after googling a lot it seems that GW2 is based in DX9 and doesn’t support SLI. Does anyone have a custom SLI Profile to force it in Nvidia Inspector or are you using the second card for SLI AA 8x or 16x?

I usually try to play games at 1440p at least and most often at 4K DSR. I know GW2 is extremely single core CPU dependent so that certainly is a limiting factor. I have a i7 6700k overclocked to 4.5Ghz at 1.28v, it’s liquid cooled so temps never top 60 degrees Celsius. The SLI I have is 2 GTX 1080 Founders Editions so the power is certainly there in my opinion.

I have been over on Black Desert Online but GW2 has always been my favorite. Is there something that can be done or is it just a “deal with it” scenario? I’ve also heard of things like CPU Cores and I currently use Razer Cortex just to optimize things a little bit for gaming.

Thoughts?

Nvidia are the ones who develop the SLI profiles. Arena Net only develops the game and implements fixes to conflicts with the drivers Nvidia develops. That being said, if you are having SLI profile issues with Guild Wars 2, I would contact Nvidia.

I am currently using 2x GTX760s in SLI. My control panel clearly visualizes I am running Guild Wars 2 in SLI mode. (see picture attached). I can confirm that Guild Wars 2 is in fact SLI capable. Running Guild Wars 2 in SLI only reduces the stress on one card and spreads it to the other (Unless you plan to run the game above 1080p).

Guild Wars 2 is mainly CPU dependent. Once you reach the graphics threshold (from my testing 1x GTX760 is beyond that), You will not see a performance increase. If you are looking to boost your FPS, I would do some research to find out if your CPU is capable of running Guild Wars 2 at the desired FPS at the desired graphics settings. For example, if I were to upgrade my graphics cards to 2x GTX 1080 Titan Ti’s, I would not notice an FPS increase unless I was comparing my previous 4k resolution settings to the hypothetical new one. This is because my CPU would be the part that is holding my PC back.

I would try setting the following settings in the Nvidia Control Panel after making sure your drivers are up to date:

GLOBAL SETTINGS
-Power Management Mode: Prefer Maximum Performance
-Threaded Optimization: On (Allows games to take advantage of multiple cores)
-Triple Buffering: On (Smooths out V-Sync if FPS drop below refresh rate)
-Vertical Sync: On (Locks frame cap to refresh rate)

PROGRAM SETTINGS (Guild Wars 2)
Make sure all of the above settings are using “global settings”
-SLI Rendering Mode: NVIDIA Recommended (SLI)

I would say it is unlikely that ANet will recode the engine to become efficient enough that SLI would make a difference with a pair of GTX 1080s.

You see SLI works best when the game engine can start creating the next frame’s commands issued to a 2nd GPU while the first GPU is processing the previous frame. The faster the GPU, relative to the CPU command generation portion of the game engine, the less of an impact a 2nd GPU makes. So a super fast GPU like the GTX 1080 combined with the slow single thread renderer of the GW2 game engine translates into a game where SLIing a pair of GTX 1080s will make little difference in performance.

My two copper.
