Just a quick question and I apologize if it's been answered plenty of times.

 

I updated from 2.05 to 2.06. When I started the game, the opening menu denotes at the bottom left side that I'm running 2.06/32. I'm assuming that means 32-bit. How do I get the 64-bit build. The executable to install  (tdm_update.exe) doesn't have a 64-bit version. Was there a choice somewhere during the install asking if I wanted 64-bit and i missed it ?

I did run the normal update from 2.05 with tdm_update.exe and got an TheDarkModx64.exe...

In your main folder you will now find tow exe-files: TheDarkMod.exe and TheDarkMod64.exe. If you use shortcuts just refer to the latter and you will always start the 64-bit version.

Thanks to both of you. If I had opened my eyes a bit more I would have seen TheDarkModx64.exe file immediately below TheDarkMod.exe file (which was pinned to the taskbar). Delete old shortcut with new shortcut and problem solved. I should have figured that one out myself  :unsure: :D

I will recommend you test both.

Some have found the 64-bit executable is consistently smoother.

In my testing, however, the most pathological shadow casting scene ( corner view in he mission Rightful Property ) is 17% slower on the 64 bit executable.

Edit:

 

Some details:

 

Current 32-bit = 48FPS

Current 64-bit = 39FPS

 

Both with "Shadow Mapping" at 1024 resolution = 70 to 80FPS...

Curiously on Intel it's not the slowest view. Looking at the main street from its end so that the fancy mansion is on the left is even slower

Did you try our performance tuning guide:

Both with "Shadow Mapping" at 1024 resolution = 70 to 80FPS...

Tracked as #4832.

 

The tragedy of shadow volumes is not that they are slow per se, but that their implementation is covered with ifs/branches which are slow on current hardware :o

You might want to check revision 75057506 (but it only affects stencil shadows FWIW)

What is your CPU btw?

OK this is pretty nice:

 

64-bit with r_ignore 0 = 47 to 50FPS

64-bit with r_ignore 1 = 57 to 60FPS

 

32-bit with either r_ignore mode = 38 to 41FPS 

 

32-bit has been lower in SVN for awhile so this is not new change.

I think this slowed the 32-bit side after we branched from 2.06: http://bugs.thedarkm...iew.php?id=4681

 

It would be cool if we could keep performance as high as possible in both but I think the point here is

"considering dropping 32-bit"?

 

I have an i3-2130 3.4ghz CPU with a Geforce GTX 1050 GPU.

Hey, that's like the absolute minimum for AVX :rolleyes:  One generation back, and you're out of luck.

I should add the SSE version of it now.

...

Please try revision: 7507. It looks like the data align might have been a problem.

Latest SVN revision with com_tempAllowAVX, both 32-bit and 64-bit have about 55FPS. Nice. :)
