32 bit or 64 bit version must be used ?

[GegeTS]

Hi all,

I have W7 Pro 64 bit and I ask if I must choose the 64 Bit ETS2 exe if that bring some difference instead 32 bit version of the game.

I ask this because I use Logitech profiler (with a G25 wheel) wich call the game executable 32 bit file.

Is there any difference between this two versions of the game executable file ?

since I have found out they had the 64 bit .exe to test I have been trying it. There is zero difference between the two.

Ok margalus but I ask if the 64 bit version is compatible with Logitech Profiler software... Because the LGS is pretty old now and possibily cause crash when calling the 64 bit version of ETS2...No ?
I ask if someone else use the 64 bit version using also the Logitech Profiler at the same time...if there is no issue...

[margalus]

I don't have a wheel, so I can't say for sure. I do use the Logitech Profiler with my keyboard and have not had any issues with the 64bit .exe. Go ahead and try with the 64 bit, it won't hurt anything to try. I suspect that it will be fine. Or just use the standard 32b .exe since the 64bit doesn't do anything special anyway.

Ok thank you for you quick answer. I'm going to try with the 64 bit version called by the profiler.

The 64bit executable is claimed by SCS to be "experimental".
To attempt to answer your question, x64 (64bit) chips "do things" faster than an x86 (32bit) chip.

An x86 OS can only access up to 4gb RAM, no matter how much is installed.
An x86 OS cannot run 64bit programs.

An x64 OS can access much more RAM.
An x64 OS can run 32bit programs.

The larger RAM access may be the "future" reason why SCS has written a 64bit executable. Perhaps to test for upcoming titles, eg ATS, so that it can handle 4K textures? Yes, I know the graphics card does all the pixel work, but the program still has to "keep up", as it were.

Thank you room217au for these accuracies. If I get some trouble or crash I will revert back to 32 bit.
Going to try the 64 bit experimental

I don't know if I'm imagining it? But the 64bit version seems to run better?

for me they are identical in performance

[GegeTS]

I'm going to try it. Enabling in the Steam properties - launching option = -64bit

[GegeTS]

Humm... It seems running like a charm without issue. What I can observe looking over my LCD logitech G19 keyboard panel is that use less CPU than with the 32 bit version. My first impression. Now I haven't used fraps for looking at FPS. Will try that later...

I've seen other posts here about FRAPS and ETS2, and they all seem to say that fraps can stop the game from starting. I can't say as I remember any of those posts specifying whether it's 32 or 64 game though.

people say all kinds of things... I have fraps and evga precision x both running 100% of the time an neither cause problems..

Yeah I don't put a lot of stock in some posts. I believe 99.9% of the time it is the user's system setup that causes the issues.

Ok Tried with Fraps = no problem at all running eurotrucks2.exe 64 bit between 60 and 45 FPS depending of the amount of scenery + scaling in game option to 300. Here GTX 580 1.5 Vram CPU i7 965@3.2Ghz stock - SSD Intel 480 Go with ETS2 on - 12 Go ram @ 1333 Mhz.
Happy with the 64 bit version of ETS2.

Thank you all for the infos and advices.

Good stuff.
