Status: offline 		My last head to head game ended in 2015, now thinking of getting back in. However, new laptop (2017) doesn't like the game, as there is massive lag. In going through the forums I have found and tried several "switches" if that is the correct term. I am not a techno wizard. I have tried:

"C:\Matrix Games\War in the Pacific Admiral's Edition\War in the Pacific Admiral Edition.exe" -f -pxf1920 -pyf1080 -archive -deepColor -multiaudio -dd_sw -altFont

-f -dd_sw -deepColor -fixArt -SingleCpuOrders -altFont

-wd -pxf1920 -pyf1080 -archive -deepColor -multiaudio -dd_sw -altFont

None of these have solved the lag problem.


I have a HP Pavilion 15-bc051nr, it's a somewhat fast unit for video editing.

specs are......

Intel® Core™ i7-6700HQ with Intel® HD Graphics 530 (2.6 GHz, up to 3.5 GHz, 6 MB cache, 4 cores),

6 GB DDR4-2133 SDRAM (2 x 8 GB),

and graphics 6 GB DDR4-2133 SDRAM (2 x 8 GB)

Massive thank you if any one has any ideas.

regards,
Terry

Status: offline 		If you have the latest update to Windows 10 (version 1709 a.k.a. Fall Creator's Update) initial reports are that removing -dd_sw clears up the lag. This version of Win 10 is the only instance I've heard of where -dd_sw isn't a help; otherwise it's a standard recommendation to use it.

You can find out what version you have by hitting the 'windows' key, typing in 'cmd' clicking on "Command Prompt" that pops up at the top of the Start Menu, and then typing at the prompt 'winver'.

Try -cpu2 or another cpu# switch. The problem is the game doesn't work well with multi-core processors. The game engine makes calls that create another thread and then waits for the other thread to finish. On a single core machine, the other thread runs on the same core, so it just waits for a tiny fraction of a second and the other thread finishes. On a multi-core machine, the other thread is spawned on a different core and while the first thread is going into wait, the second core is done and every core sits around waiting for the other to do something. Finally after a timeout of something like a second, the first thread makes the call again and discovers the answer is sitting there waiting and continues.

I've really wanted to fix this problem for some time and Michael and I took a shot at it about 2 years ago. We made some progress but both of us got called away with our "day jobs" and we never managed to get it completely working. It's a case where I know what's happening, but I can't quite figure out how to fix it.

cpu2 will force the game to only use the 2nd core. The first core is often used for Windows functions and some people have had problems with -cpu1, but -cpu2, -cpu3, or -cpu4 should work better.

Yes, I suspected the 4 cores was a likely problem.

Status: offline 		I would give wdolson's suggestions a go - I've always thought of the cpu switches as more of an AMD thing, but the truth is there are so many multicore processors out there now (both Intel and AMD) that it's really a case-by-case basis to find the "sweet spot" for your PC. Of course, you can experiment with and without the -dd_sw switch along with the cpu switch.

I haven't seen any ordering requirement for shortcut switches in WitPAE. I also have a quad core system and have never had any issue once I began using -dd_sw. I also froze my Win 10 version at 1607, two versions older than 1709 (for reasons unrelated to WitPAE, but I don't mind avoiding the issues some folks have been experiencing).

Another key difference between our processors is that I have an i5 while you have an i7. Your processor has what's called "hyperthreading", which is basically a way to treat a physical core as two (so in theory you have up to 8 cores). Hyperthreading might make the -cpu switches more valuable to your PC.

-cpu2 -fd -archive -deepColor -dd_sw -altFont


Then delete -dd_sw if that doesn't work.

Lag seems mostly gone but game loads "offset" to the lower right and I don't see everything.

-cpu2 -wd -pxf1920 -pyf1080 -archive -deepColor -multiaudio -altFont


You'll have a title bar at the top, but it should center the screen.


Edit: Another thought - are you using a resolution other than 1920 x 1080? That could be a cause for the non-centered game window. You'd want to have the resolution switches match whatever you're actually using.

Then left click:
Display Settings --> Advanced Display Settings (blue link towards bottom)

It should then show you the actual resolution in the "Resolution" drop-down box.


Edit: You beat me.

You might want to tweak it to:

-cpu2 -fd -archive -deepColor -multiaudio -altFont


IF you'd like daily (in game terms) autosaves - I've found it to be a good idea. Adding -skipVideo will also automatically skip the opening video if you get tired clicking through it.

Status: offline 		I played WitP alot since it first came out. Stopped playing humans in 2015 after Dave resigned after we reached March 1944, just didn't have time. Not sure I'm going to start again but want to be able.

Thanks on the Palau comment. There's alot more coming once I reduce more pics. Maybe 3/5's done with this day trip to Peleliu. The next day we dived a shot down Jake seaplane and then there was a second trip to Peleliu off our live aboard dive boat later in the week where I saw even more.

It can be anywhere in the string of switches, but I'd put it near the beginning.

When we put those switches in we were seeing a lot more problems with Intel processors than AMD. The video card can contribute to it too.
