Slick Fork Posted May 1, 2020 Posted May 1, 2020 Hey guys, I'm struggling to get good frames in DCS and I'm not sure why. I've done the optimisation guide with new VR shaders and use all the recommended settings... My system is as follows: DCS on an SSD I7-6700K at stock Nvidia 2070SC 16gb ram Oculus Rift S Any thoughts?
Rudel_chw Posted May 1, 2020 Posted May 1, 2020 There is a simple test you can do .. lower your graphics quality settings a bit. If the fps keep more or less the same, then the cpu is your bottleneck; if the fps improve a bit, then your graphics card us the limiting factor. For work: iMac mid-2010 of 27" - Core i7 870 - 6 GB DDR3 1333 MHz - ATI HD5670 - SSD 256 GB - HDD 2 TB - macOS High Sierra For Gaming: 34" Monitor - Ryzen 3600 - 32 GB DDR4 2400 - nVidia RTX2080 - SSD 1.25 TB - HDD 10 TB - Win10 Pro - TM HOTAS Cougar Mobile: iPad Pro 12.9" of 256 GB
SVgamer72 Posted May 1, 2020 Posted May 1, 2020 Based on current state (5/1/2020) and issues reported on these forums with performance in recent patches... Order of potential improvement.... 1. DCS needs tuning/patching 2. 32Gb of RAM running 3200-3600 (you need to move data between CPU-RAM-GPU as efficiently as possible, and DCS is a RAM hog) 3. OC your CPU to as close to 5Ghz as you can get it to feed your GPU. (single threaded CPU performance is the most important factor once everything else is tuned as well as you can get it)
Slick Fork Posted May 4, 2020 Author Posted May 4, 2020 Thanks for the tips guys. I replaced my ram with an upgrade to 32gb of 3600 and got my CPU OC'd to 4.3. The difference in the RAM alone is night and day. Strangely - the carrier bogs me right down and the hornet and tomcat both are way slower than the Mirage/A-10c/F-5e
SneakyBastd Posted May 4, 2020 Posted May 4, 2020 You should be able to get way higher than 4.3ghz. Also turn off hyperthreading, that alone can give you about 10% more single threaded performance. 7700K@5Ghz, 32GB 3600 CL16, 3080.
Slick Fork Posted May 5, 2020 Author Posted May 5, 2020 You should be able to get way higher than 4.3ghz. Also turn off hyperthreading, that alone can give you about 10% more single threaded performance. I'll check out the hyperthreading. I don't know that any other programs need/use it. I think my motherboard is crap. My original Asus died last year and I had to settle for a pretty crappy bottom tier Gigabyte, it's all that was out there. Maybe I'll get a good back to school sale on something. Doesn't seem to matter how much voltage I throw at it, 4.4 crashes under about 10 minutes of stress. 4.5 is an instant crash with Prime95.
