This is a carry over from a two year old forum poll/post by @gamerinoo that has 99% votes for yes. It has still yet to be implemented even after all this time.
I think this feature is still needed in the game, and would help the entire player base, so I will do the effort of re-typing, editing, and explaining that post in my own way.
FSR 2.0+ is an open-source upscaling technology developed by AMD.
It it non proprietary (unlike Nvida DLSS), meaning that all people, regardless of the hardware they have, can use it to see meaningful performance gains with minimal to no loss in image quality.
In short, here’s how FSR 2.0+ works:
If you enable FSR 2.0+ in the settings, it will render the game at a lower resolution than the one you’re playing at. For example, if you’re playing at 1080p (1920x1080) it will render the game at 720p (1280x720) therefore increasing your framerate in game. To prevent quality loss by the lower resolution, FSR 2.0+ will use data from multiple past frames, jitter of the past images, and motion vectors (the technology already built into the game to allow DLSS (nvidia only) to work) to reconstruct the image to a higher quality, close to the original resolution.
FSR 2+ doesn’t require proprietary hardware to enable it. In fact, it also is supported on all modern consoles (Including: PS4/PS5/XBOX ONE/XBOX SERIES S/XBOX SERIES X), it just needs to be enabled. FSR 2+ also works on integrated gpu’s (of both AMD and Intel), unlike DLSS, which requires modern, full size GPUs of the RTX generations.
Here’s a few example of FSR 2+ in action in a game that already implemented the feature (the game is deathloop and the screenshots taken by @gamerinoo)
Here’s for example a 720p image on the left, and the same 720p image on the right but reconstructed by FSR 2.0. As you can see the image is much clearer and sharper, and all of this while being bearly harder to render.
Here’s how a 1080p image on the left compares to the same image at 720p reconstruced by FSR 2.0 on the right . keep in mind that the 1080p image that you see here was harder to render for the pc and therefore the fps was lower for on the 1080p image.
So the image quality is similar to 1080p when the game is rendered at 720p and improved by fsr2.0.
1080p image on the left compared to the same image at 540p reconstructed by fsr 2.0 on the right. At this point we can see that the reconstructed image is worse than the original image, but the performance gains a huge (almost 100% more fps) making it useful for people that struggle running the game but still want good visual clarity.
War thunder has been evolving its engine and increasing texture sizes and effect density over the last few years, and it is straining some of their players computers. They are also pushing VR a little harder recently, and VR already itself requites 2x more horse power to run the game. This feature would make the game more enjoyable for a lot of players. It will also enable the devs to push the graphics and not worry about the console market as much, thanks to the performance headroom FSR could offer.
Here are the key take aways:
- FSR 2+ open source code is freely available to any game developer, and AMD will even send free game engine technicians to help developers implement it (if you request it and your game is big enough).
- FSR can give ALL PLAYERS, no-matter the hardware, free performance at almost no image quality loss.
- The back end technology is has been in war thunder for over 4 years now, adding FSR2+ to the game would take minimal effort. Some develops have openly stated they got it implemented into their games in under 3 days.
- It works on consoles and handhelds (like the steamdeck) too, so the game can keep being pushed technology wise, since they can offset performance loss form new features with FRS performance gains.
- It helps EVERYONE. It is a non-proprietary tech that works on hardware that goes back 10+ years.
Would you want Gaijin to put FSR 2+ in War Thunder?
Note: The pictures in this post are old, from the FSR version 2.0.1 days. The current version is FSR 3 (based on 2.2.2 with frame generation technology and other stuff added now), which has fixed several issues like motion blur artificing, low light jitter, and giving even more performance in some situations. Expect the in game implementation to be EVEN BETTER by a noticeable degree.
- No (please explain why)
