I also use process lasso, assigned exclusively DCS to core 0-7 without HT. I can imagine that other optimizations (like the flat-shadow fix) are even more responsible for this. AH64 on the Marianas map in a mission I get easily 45fps. Interesting: I consistently get lower CPU and GPU times in all maps and airframes: (app CPU in the F15 in Nevada is below 1 ms ). Not that it matters because even if I force it to run on v-cache, there is no perceptible change. Reverb G2 with 150% OpenXR resolution and max settings (except 2x MSAA)Īlso, the MT DCS is running on my non v-cache core for some reason even though I have it set to prefer v-cache in Process lasso. Guess I should reduce some settings because 15 ms is way too high with a 4090. Meanwhile, my GPU frame time ranges from 12-15 ms. My CPU frame time was already 3-4 ms which is very good so I don't think it could have improved much. No change for me because I was probably already GPU bound
I just went from low shadows to ultra, enabled cockpit global illumination, from 60% trees to 100% and all is still perfectly smooth (higher FPS than before MT update).Ĭompare below the OpenXR CPU and GPU frame times in Single threaded and Multithreaded: F-18 on carrier ramp in Persian Gulf: So far I have never seen CPU time more than 10ms. When starting a mission, you can see all textures (plane and ground) being loaded in. Did not expect this, because with a 4090 less GPU bottlenecks are experienced.ĭCS MT seems stable so far, no CTDs yet, but only limited/quick tests of many different missions and instant actions. The positive impact on CPU also affect GPU response times favorably. Both Syria and Marianas maps are clearly much more smoother/responsive. DCS feels much more snappy and responsive. Obviously MT is much smoother, there are less stutters, but maybe more noticeable: input latency improved considerably (might be placebo). MT is even better, improved by 2-3 ms GPU frame times in the F16 in the above Dubai and Marianas. I improved by 1-2 ms GPU frame times in the F16 in the above Dubai and Marianas in single-threaded. I prefer to fly with Flat-shadows, which clearly is smoother. Good news maybe if MT does not work for you, it looks like single-threaded DCS is also much smoother.Īfter more testing, I can also safely conclude that single-threaded is also much more smoother and responsive. Seems like there have been more optimizations having a positive impact (ie Shadows flat bug). Single-threaded openXR shows 5.1ms app CPU and 4.2ms rdr CPU times.
F18 ready for launch on Carrier: now openXR shows 3.3ms app CPU and 3.2ms rdr CPU times.
