The system would then select the most appropriate battery for each one, and hand off particular targets for them to attack. Each MAR, and its associated battle center, would process tracks for hundreds of targets. MAR allowed the entire battle over a wide space to be controlled from a single site. Using a variety of beamforming and signal processing steps, a single MAR was able to perform long-distance detection, track generation, discrimination of warheads from decoys, and tracking of the outbound interceptor missiles. The MAR (Multi-function Array Radar) was made of a large number of small antennas, each one connected to a separate computer-controlled transmitter or receiver. ZMAR became MAR when the Zeus program ended in favor of the Nike-X system in 1963. The result was the Zeus Multi-function Array Radar (ZMAR), an early example of an active electronically steered array radar system. Sketch of the FLAT TWIN antiballistic missile radarīell Labs proposed replacing the Nike Zeus radars with a phased array system in 1960, and was given the go-ahead for development in June 1961. AESA radars can spread their signal emissions across a wider range of frequencies, which makes them more difficult to detect over background noise, allowing ships and aircraft to radiate powerful radar signals while still remaining stealthy, as well as being more resistant to jamming. The AESA can radiate multiple beams of radio waves at multiple frequencies simultaneously. The PESA must utilize a Butler matrix if multiple beams are required. PESAs can only emit a single beam of radio waves at a single frequency at a time. The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. AESA's main use is in radar, and these are known as active phased array radar (APAR). This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. You really need to fly in ovc, low viz conditions to see the FPS drop.The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antennaĪn active electronically scanned array ( AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. If I happen to see it happen again I will try to save the info (date, time place) and forward it to your team. In two months of flying I've only had this occurence twice, a perfect storm if you will, of conditions to cause the FPS drop. I understand you cannot reproduce these issues and reason being the wx has to be just right. I'm also using ASCA clouds at 512k resolution and personally do not think they affect the FPS except for possibly when depicting cloud structures such as TS, there may be an occasional drop in frames.
#Active sky next low fps 1080p
I have since reduced resolution back to 1080p and 60hz to see how it reacts to multiple viz layers. One point about the test above is I am running a 4K monitor at 30hz with no SGSS etc so mine may be extreme to due have to render 4 times more pixels than most. I really do not think a solution will be found as todays GPU's cannot handle the stress put on by heavy clouds and multiple viz layers at 200 miles. I think the multiple viz layers will kill an ordinary GPU while also trying to depict clouds etc up to 200 miles out. The above issue can last 30-45 minutes depending on weaher conditions. On occasion I will have a drop in FPS of about 5 fps when the weather is updating and new textures are loading in but this only lasts up to 3 minutes if that long. (I7-6700K 4.6, 980TI)Īfter seeing the GPU at 99% I changed max upper viz to 200 from the original setting of 199 and immeadietly after the changes my FPS went back up to 30 and GPU usage dropped back to a normal 75-80%. I noticed the drop in FPS so I pulled up NVInspector and noticed my GPU was running at 99% while my CPU was only 35%. I had this happen on my last flight in the Constellation (which is not hard on frames) from ORD to BNA. Upon entering another interpolated area FPS jump back up to 30. At certain points, depending on weather, my frames go from a consistent 30 down 10-19 and stay there for some time. The FPS drop for myself is within P3D v3.4.
