Please describe your issue in as much detail as possible:

Trying to launch CS2 without any "launch options" gives this error: /home/b3z/.steam/debian-installation/steamapps/common/Counter-Strike Global Offensive/game/cs2.sh: line 115: 7930 Illegal instruction ${STEAM_RUNTIME_PREFIX} ${GAME_DEBUGGER} "${GAMEROOT}"/${GAMEEXE} "$@"

Steps for reproducing this issue:

Push the button "PLAY"

Your CPU is quite old. CS2 is likely compiled for x86-64-v2 (or perhaps newer), whereas your CPU only supports x86-64-v1.

Also dmesg show me this: traps: cs2[32244] trap invalid opcode ip:7f1fd0038c4e sp:7ffe4ecb5f70 error:0 in libtier0.so[7f1fcfebf000+2f3000] This may suggest that the library libtier0.so was compiled with a instruction that is not supported on my processor.

The issue is that the game now requires SSE4.2 Instructions for some reason. https://github.com/ValveSoftware/csgo-osx-linux/issues/3320 https://github.com/ValveSoftware/csgo-osx-linux/issues/3394

Edit: No, based on the bug numbers: this one was first, making the others duplicates.

Edit2: I also consider the lack of a meaningful error message a bug. There are instructions for testing CPU features: the game should use them.

That is all well and good: but the minimum system requirements say nothing about requiring as specific x86-64 version.

The exact wording at the time of this writing is:

4 hardware CPU threads - Intel® Core™ i5 750 or higher

OP's CPU mostly meets those requirements.

According to CPUBenchmark.net: a score of 2526 is the one to beat.
OP's Intel Core2 Quad Q9550 @ 2.83GHz is a little under that score, but within the margin of error on synthetic benchmarks, with a score of: 2326
AngryPenguinPL's sysinfo does not show the exact CPU model; but it looks like the fast (3Ghz -- 1075T) version of my AMD Phenom(tm) II X6 1035T Processor (2.6Ghz). 6 cores help a bit with synthetic benchmarks, landing at 2962
@PedriNH4x, who filed the second bug report, has an Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz. With only 2 cores (no hyperthreading), it does not meet the the Minimum system requirements. Score: 1192 Note: this CPU implements SSE3, SSSE3 and SSE4.1, while the faster AMD Phenom II does not (it does have SSE4a -- not the same)
@blogdron, who filed the third bug report, has an AMD Phenom(tm) II X6 1055T Processor. It has a clock speed of 2.8Ghz, scoring: 3289
Edit: Bonus comparison: Intel Core i5-750 @ 2.67GHz vs AMD Phenom II X4 965 They look directly comparable to me: even approximately the same release date (Q3 2009)

Those CPUs are all older than the i5 750, therefore I wouldn't exactly call it "higher". If they wanted to, they could've specified these older but allegedly equivalent CPUs instead if it was just a performance problem. Furthermore, using a weird synthetic benchmark that utilizes all the cores does not represent the actual gaming performance of any of these CPUs.

OP's Intel Core2 Quad Q9550 @ 2.83GHz is a little under that score, but within the margin of error on synthetic benchmarks, with a score of: 2326

I would not call 7% margin of error

That is incorrect; the 6 core AMD parts were released in 2010:

intel core i5-750 (2.67GHz) release date: September 2009; Single Thread Rating: 1233
Intel Core2 Quad Q9550 (2.83GHz): March 2008; Single Thread Rating: 1221
AMD Phenom II X6 1075T (3.0Ghz): Sep 21st, 2010; Single Thread Rating: 1387
AMD Phenom II X6 1035T (2.6Ghz): Apr 27th, 2010; Single Thread Rating: 1227
Intel Core2 Duo CPU E8400 (3.00Ghz): Jan 1st, 2008; Single Thread Rating: 1236
AMD Phenom II X6 1055T (2.8Ghz): May 1st, 2010; Single Thread Rating: 1326

Edit: the "single thread" ratings may be hiding poor IPC.

Good point, my memory is a bit hazy it seems. Although the Phenom II lineup did come out in 2008, I feel like that's being very nitpicky. Valve should probably just specify that SSE4.2 is required, or specify a minimum of an FX-4130 for AMD.

phillipsjk commented 12 months ago

They can make the [Bulldozer] series, supporting [SSE4.2], a minimum system requirement if they want.

I have no real dog in this fight: only wanted to try now that it is "free to play". I feel for the people who paid [for] CS:GO, and now can't play CS2 due to higher requirements.
