Since migrating to a DX11 renderer in the future isn't an option, I'd be curious if the devs could improve performance with further objects optimization. The CPU is overloaded with submitting a large amount of draw calls which unfortunately are only processed on a single CPU core/thread in DX9. As a result, the frame rate is being limited by the number of objects. Which makes sense since Rising Storm is typically a lot busier (more detail and objects) in any given scene which means more draw calls. Very smooth and consistent FPS at maxed out settings and high GPU utilization all the time.

But other than that, the FPS drops occur whether I've got my settings at lowest or maxed out and when I reduce resolution.īy contrast, Red Orchestra 2 runs great. Turning Foliage Quality to Low seems to be the only thing that has made any significant difference in my minimum FPS. It's primarily the object count that's causing the CPU bottleneck, which is why performance is worst on the foliage-heavy maps such as Hanto and Guadalcanal. Unfortunately, there is currently no way to force high quality AA in DX11 games, so we are stuck with low quality ingame MSAA, FXAA or TXAA, possibly combined with Driver Downsampling.įor this reason, 'aufkrawall' from the 3DCenter forums started a petition on the GeForce forums to extend driver-forced AA to DX11 mode:Ĭlick to expand.I've already got Shadow Quality on High and Occlusion Quality Normal. The actual list of DX9 AA flags consists of the first two posts on page 1, and is updated regularly.įor example does SGSSAA also work wonderfully in the DX9 modes of Crysis, Crysis 2and Metro 2033.Īnother good example is the DX9 mode of Battlefield: Bad Company 2, which really shines with driver-forced SGSSAA and completely puts the ingame AA modes in BF3/4 to shame. SGSSAA works great in hundreds of DX9 games, most of which can be found in the very comprehensive AA sammelthread at the German 3DCenter forums.

In general driver-forced DX9 SGSSAA is a wonderful NVIDIA exclusive feature IMO. I also found a better SLI profile '0x02422605', which solves random drops in GPU usage in SLI mode. Using NVIDIA Inspector, you can force beautiful SGSSAA using the '0x080000C1' AA flag. I have been working hard on completing an SGSSAA/SLI/tweaking guide for Rising Storm & Red Orchestra 2.
