    Post 16 Update

    Post 17 Warning old domain name stealing credentials

  • IMPORTANT INFORMATION - ALL MEMBERS PLEASE READ

    Due to an increase in the number of new members who are trying to systematically download our entire Resource Library (one new member yesterday tried to download 3,000+ files AT ONCE!) we are being forced to implement some changes regarding who can download what, how many files at a time and at what speed. As the forums and Resource Library share the same bandwidth when the Library gets overloaded with demand like that the forums fall over, as we have all seen recently. It's sad that greed has forced our hand in this way but we must do something for the benefit of all our legitimate members (many of whom paid money for the upkeep of the site) and to prevent the files stored here being used for nefarious purposes. Many of our uploads have specific conditions tied to them that forbid uploading to any other site or deny uploading to any site that has a 'paywall' (i.e. a pay to download policy). Due to the number of mass download attempts recently we can only assume that somebody, somewhere, is attempting to stock up a new file library with our files and we owe it to our up-loaders to protect their files and intellectual property especially as many (like my own LDR Development projects) are made available at SOH only and are specified as such in the 'read me' files.

    The forums and Resource Library will be taken offline as of 13:00 EDT with the forums coming back online shortly after without the resources library while we work on setting up permissions on the new Library module.

    We hope our members understand why we need to do this and will bear with us while we implement the changes.

    Thanks in anticipation, SOH ADMINISTRATION

    Downloads are now active. You may proceed with downloading as desired

    The download limits are a work in progress. Some settings are likely to need tweaking in the coming days.

Version 4.1

This is a very useful and informative discussion.
I would like to pick up your suggestion, Gordon, and ask if you could open a new thread with a related title to further explore this matter.
I'll sticky it because there 's a lot of useful information on how to tune p3d 4.1 to specific systems.


Thanks,
Mark

btw.
gman5250 I see You have V-sync off and You wrote about 100 fps, so do You have G-sync and monitor with refresh rate 144? If V-sync isnt ticket You dont see screen tearing on monitor ?
V-sync/G-sync limits fps to refresh rate of monitor, so for example I setup my monitor to 60 Hz, and in P3D I see 60 fps max, not more (so level of Hz of monitor, btw max my is 144). However, Fall Creators Update Windows 10 (3-4 November) causes problems for P3Dv4 with this.

Screen resolution 1080p, 1920 x 1080
Monitor refresh is 60HZ.

In all of the video I have shot, V-sync has been off and texture filtering as I posted earlier. I've never had any tearing, not even in the raw video cap. I've also found that texture filtering, at least for my monitor resolution doesn't have to be at the highest settings. If I do turn V-sync on with triple buffering, FPS drop down around 60. Still good for video, but there is no benefit for me using V-sync.

I'll do that today Mark.

We can get the topic going with some guidelines and parameters. I'll follow up with a video showing my setup A-Z and live charts, FPS etc. It's a lot more comprehensive when you watch the data through all of the peripheral monitors.

I think it will be a helpful tool, seeing as P3Dv4 is such a diversion from everything that went before. I'm still deep in the learning curve, but I am getting super results so far.
 
Gordon, is affinity mask only for hyperthreading CPUs? I have an i5 7600k, no affinity mask, and P3D keeps Core 0 at 100%, and the other three are evenly distributed according to load. Total load maxes out over NYC at around 65%, 40-50% everywhere else. I figured out any stuttering I saw was from the GPU (6GB GTX 1060) exceeding 100% usage (heavily-forested with cloudy/hazy weather), and changed my settings so it never uses over 90% in those situations. I get to keep PTA, yay!

Affinity mask can be utilized with hyper-threading disabled or enabled Pat. You can manage those settings through your BIOS.

The calculator will create a curve based on the parameters you check in the setup menu. There is a tick box for hyper-threading. Just leave that un-checked and the number will be calculated based on that parameter.

The calculator will work for dual core, quad core, hexacore and octacore processors, and there are two menu options offering Easy and Expert modes.
 

I did test with AM=255 and AM=116 (like on this video).
It looks like 116 gives more stable/smooth picture. Must to try more, after few days I'll know its a good option for me or only placebo effect :biggrin-new: (for i7, HT=off).

For us simmers, any discussion of Affinity Mask must be accompanied by an explanation of which external add-ons we use (much as Gordon did a couple posts ago).

Steve Waite (http://codelegend.com/) has some interesting discussions and points about Affinity Mask and Logical Processor (LP) configuration over at Avsim. The two most important facts I've learned from him... P3Dv4 must be configured to minimize thread crashing (especially critical for the first LP the sim uses) and always include your external add-ons when considering an Affinity Mask (for any sim but especially for P3Dv4).

Hi
Tried using Affinity Calculator (http://www.gatwick-fsg.org.uk/affinitymask.aspx?SubMenuItem=hardware), not sure how to use Expert mode...my CPU i7-3820 4 cores 8 threads...got value 84 in easy mode, would like to make sure with expert mode. Please help
Regards

Go into Expert Mode and:

1. Tick hyper-threading enabled. The page will reboot and give you the expanded menu in Expert Mode.
2. Tick all of the boxes for 0 thru 3 for Logical and Thread.
Example: Logical 0, Thread 0, Logical 1, Thread 1, Logical 2, Thread 2, Logical 3, Thread 3.
3. Select Calculate. That should give you your number.

Thanks, Gordon. I ran the calculator for 1111 (AM=15, default, I guess), 0111 (14), 1011 (13), 1101 (11), and 1110 (7). With affinity masks of 13, 11, and 7, Core 0 stayed at 100%, the core set to zero was very low, and of the other two cores in use by P3D, one was always twice as high as the other (often nearing 100%), so really not as balanced as it is by default for me. No noticeable increase or decrease in FPS, still no stutters. With affinity mask of 14, Core 0 was really low, and the other three were often running at 100% simultaneously, stutters galore. So I'd say I HAVE to have P3D use Core 0. Since I see more balance with default, I'll stick with that for now. Thanks again for the help.

LOL... why would they password protect that file!! I haven't had to replace the file since I started using it almost 4 years ago, but found a link at this simming site: https://www.sas1946.com/main/index.php?topic=32520.0 The password for the calculator is "sas1946" (without double quotes).

HTH,

Thanks for the follow up. This little program is very handy and better than an online one from a website which one day might disappear.
