  1. I remember reading here that add-on aircraft will sometimes use libraries/routines/textures etc. from the defualt aircraft. Deleting them might cause unexpected failures in other products. I might be wrong overall, and it might not apply to your add-ons, but be cautious. Scott
  2. Completely non-P3D point here, but I've worked with some setups that mix a 4k monitor with a non-4k monitor. Windows 10 does a much better job of scaling programs between different DPIs than it used to, but it doesn't always handle changing dpi on the fly. If you drag a window from a high-dpi (i.e. 4k monitor) to a regular-dpi (your existing 24"), you may have programs that do not scale interface elements immediately, rendering them unusable. (They work fine when started in a high-dpi environment, but don't handle changing without restarting.) I love working on my 4k monitor as a single large display. I treat it like having 4 normal monitors in a seamless grid. I sit close to it and leave the scaling at 100%. I can spread a program horizontally across the width of the screen (e.g. Excel), or vertically across the entire height (for code listings). There are free utilities out there that let you define complex custom snap points that make it really easy to make use of all that space. My guess is you'll quickly forget the additional monitors.
  3. I had an ultra wide computer monitor (43" 21x9 ratio) and switched to a 47" 4K TV with a standard 16:9 ratio. I couldn't be happier with what it does for P3D, not to mention other things. I even liked it so much for productivity tasks that I convinced my company to buy one for my office. Check out https://www.rtings.com if you don't know about it. Many of their TV reviews specifically address using the TV as a computer / gaming monitor. You tend to sit a lot closer to a TV being used as a computer monitor so it's helpful to have a review from that perspective. They saved me because the model I was going to buy had some visible cross-hatching from up close. It was not noticeable from room-sized viewing distances, but at a desktop distance it was like looking through a screen door.
  4. I upgraded my i7-4790K to the i7-8086K. With a good air cooler, power supply, and case, I'm able to run it at a constant 5.2 GHz. I wasn't necessarily hunting frames, but I was able to turn the settings in P3D up even further and maintain what I wanted, especially in dense scenery and heavy clouds. Still can't get into LAX without seeing a drop, but I fly with ORBX SoCal, UT Live, the works. Almost anywhere else I fly I can get the performance I want without compromising. As I understand it, the 8086K is the same processor as the 8700K, but Intel picks out the best quality ones and brands them as the 8086K. Using only the best chips allows them to bump the boost frequency to 5 GHz out of the box. The way I see it, an 8086K is much more likely to hit the higher speeds than an 8700K. Is it worth the price premium? It was for me. I've also seen that the newest Intel chips (the 9XXX series) might not be the best when overclocking either (example: https://www.anandtech.com/show/13400/intel-9th-gen-core-i9-9900k-i7-9700k-i5-9600k-review/22) The new chips are faster out of the box, but Intel seems to be shipping them at much closer to their maximum clock than they used to. It seems to be a lot more work and money to squeeze out a couple hundred MHz on them than it used to be. There may be benefits to having the additional cores, but I think P3D still has a ways to go to automatically say more cores is better than more clock. As for the 10th generation, most of the speculation is on Intel moving to a smaller manufacturing process (10nm or even 7nm). Historically, Intel moves to a smaller process every other generation (which generally improves efficiency) and then stays there while improving the performance for the next generation (referred to as the tick-tock cycle in the past). The next smaller manufacturing process is already a little late (this is the second performance increase generation) although some of the new mobile chips are using a new process. As for the Z390 motherboard vs the Z370, most of the specs I've seen refer to improvements in USB, Wi-Fi, PCI lanes, etc, and not much that really centers on the processor. At one time I thought I read that the new chipset supported faster memory, but I can't find anything now that says it. DDR4 vs DDR3 vs DDR2 is basically a generational notation, much like the 8700K is the 8th generation processor and the 9700K is the 9th generation processor. Newer generations support faster speeds. RAM speed is generally measured in bandwidth instead of frequency because a number of factors make the specific clock frequency meaningless. The general rule is to buy the highest bandwidth that the processor and motherboard support. Then you get into the timings thing, which is above my pay grade. For example, I found a 16 GB stick of ram advertised as DDR4 400 (PC4 32000) with timings of 18-19-19-39. I'm pretty sure that it's running at a 200MHZ clock frequency, but because it transmits on both ends of the clock cycle, it's transfers data at a 400MHz rate (DDR stands for Double Data Rate - two transmissions for every clock cycle). Because it can transfer multiple bits (8?) at a time, it has a total bandwidth of 3.2 MB/sec. (I might not have it exactly right, but you get the idea.) The timings (18-19-19-39) refer to how many clock cycles / how much time the RAM takes to perform certain actions such as respond to an instruction or access a specific bit. It gets super technical, but the rule is always lower is better. I believe it is possible for RAM with a higher frequency but slower timings to end up having poorer performance than RAM with a lower frequency but faster timings. I think that's only true in extreme cases, but it means you can't ignore the timings entirely. As far as an SSD goes, I can't really speak about M2 versus a standard SATA. I have a desktop with an M2 SSD, but my P3D machine has SATA SSDs. I haven't benchmarked the drives, but the computers are nothing alike in terms of the other components so I don't know that it would be meaningful anyway. I honestly I can't say I notice any difference between them, but that's doing normal day-to-day tasks. I also don't think that P3D is particularly sensitive to disk speed above a certain point once you're flying. That may be different for photoreal, which I don't use. I've never felt that the SATA SSD I have was holding me back. Moving from a traditional rotating disk to an SSD is such a massive game changer, but I don't think an M2 makes quite the same impact. I guess what I'm trying to say is that in my opinion it would be better to make sure you have everything on an SSD, even a cheaper and slower one (non M-2). I also understand that the M2 format drives do generate a lot of heat under load. My ASUS motherboard came with a special heat sink just for the M2 slot.
  5. As noted, 4k refers to the resolution of the display device (monitor, projector, tv, etc.). Getting a 4K signal to the display device can also be an issue. Not all computers can do it, especially laptops and systems using the GPU devices integrated into the motherboard or CPU. You'll also need a newer HDMI or display port connection between the computer and monitor - older HDMI cables, DVI, and VGA cables can't do it. Assuming all of the hardware is in place, you might still have to tell your computer to output to the 4k signal. Windows will try to output at the optimal resolution (i.e. the one that matches your display), but you may have to tell other programs (like FSX, P3d, etc.) to output at the higher resolution. Not having the proper drivers installed could also limit you to a lower (non 4k) resolution.
  6. In my opinion, stick with Intel over AMD for now. P3d is still very much a single threaded program (LM has made a lot of improvements, but the speed of a single CPU core is usually the limiting factor in performance). That means you should take into account single core speeds instead of overall processor benchmarks. Passmark has an easy way to look at the overall benchmark (https://www.cpubenchmark.net/high_end_cpus.html), and a single-core benchmark (https://www.cpubenchmark.net/singleThread.html). The i7-7700k is pretty far down the list of high-end CPUs and well below that of several different AMD options at lower prices. But for a single core, the i7-7700k is near the top and well above anything by AMD. Passmark's benchmarks may not be rigorously scientific, but I think they illustrate why there's not really a 1-1 match between Intel and AMD, and why Intel is a better option for P3D. (This is also why many advocate disabling hyper-threading on Intel processors; sharing one physical core between two logical cores means a potential performance hit to single core speed. That performance hit may or may not outweigh the benefits of have more logical cores depending on the system - the evidence is not completely clear cut.) The i5-8600K (FunknNasty's CPU and the one recommended by Nickbe) has a single-thread score on Passmark that is only 2.4% less than the i7-7700K that you are considering. It is an excellent option at a lower price. But everything in your system has an effect. P3d hits a lot of components pretty hard, and upgrading one component (e.g. CPU) can reveal that another component (e.g. RAM) was running at near 100% capacity. So instead of getting a 10% boost from an upgrade, you only get 1% or 2%. That's why you want to pay attention to things like RAM and disk speed as well. Don't discount over clocking either, which is going to be greatly affected by the case and cooling system you put with the CPU. Even if you don't want to mess with voltages or timings, you can squeeze some GHz out of a CPU by using the motherboard's "automagic" overclocking routine, but the key is keeping things cool. My Asus board automatically bumped my i7-4790K from 4.0 GHZ to 4.4 GHZ, and I was able to get it to 4.6 GHz without trying hard and doing anything exotic like de-lidding or water cooling, but I bought a very nice air cooler to do it. That made a bigger difference in performance than the upgrade in the first place.
  7. This is a bit technical but may be appropriate to your situation.The users at my company (where I am the IT manager) had all sorts of problems with staying logged into a number of websites (very similar to what you are describing). The culprit turned out to be our new security hardware that was inappropriate assigning different ip addresses to ongoing connections. It made it impossible for websites to recognize incoming traffic as being from the same computer. Each time a user went to a new page, the request appeared to be coming from a different computer, so users were constantly being asked to re-enter their credentials and shopping carts would mysteriously empty. (Not that employees were supposed to be shopping at the office.) Not all websites were affected; it depended on how the websites maintained the session information. Cellular phones have features like MAC Address randomization that might cause this symptom; your gateway/router/firewall software could also be providing similar functionality as a privacy feature. Some VPN services could also do something similar as part of the anonymization processes. I don't have anything specific to point you at, but you might take a look at how you are connecting to the internet as something to test.
