First of all I have tried every solution I could find:
gl_vsync, gl_ansio, fps_max, nofbo, nomsaa, nohd, soft etc.
Before update everything was ok (~80 fps). Now I can't play because of low fps in menu and game itself. I think it may be a problem with video card GeForce FX 5200 as it's not the newest one ;) but I never had a problem with it.
Here's what I've got:

Nvidia drivers - I use version 175.19 as they are recommended for this card by nvidia.com. They are not the newest but I never have a problem in any game I want to run.

CS version from console:
Protocol version 48
Exe version 1.1.2.7/Stdio (cstrike)
Exe build: 15:00:41 Feb 13 2013 (5956)

And OS info:
http://pastebin.com/a8hi0Xpm

It's almost fresh install of WinXP and I also reinstalled Steam and CS.

Put '-nofbo -w 640 -h 480' into the games launch options (in the Steam Library list) and try running, see how that helps.

It didn't. Now it's 5 fps.

Try:
'-soft -w 640 -h 480'

@m3x Did you use to play in D3D?

@alfred-valve It helps, at least in game menu, but cs in unplayable in software mode - low fps (net_graph doesn't work?) I guess around 20-30 fps, weird textures, black bar on bottom of the screen. Not normal cursor clicks - I mean I need to click under element (i.e options' tabs) to actually click it.

@Egon-Spengler No. I always play in OpenGL.

i think cl_showfps 1 should work in software mode

Okay, launch with:
-nofbo -w 640 -h 480

and then when the game is running type this into the console:
gl_texturemode GL_NEAREST_MIPMAP_NEAREST

and see how that helps.

In game it's fine now. But in menu still 4 fps.

@m3x, so to be clear for me, if you launch with:
-nofbo -w 640 -h 480

and then run:
gl_texturemode GL_NEAREST_MIPMAP_NEAREST

You see your original 80fps or so when in a map?
But then if you hit esc you drop to 4fps? But if you hit esc again (to dismiss the menu) you go back to 80fps right?

Yes, when in a map. And if I hit esc, it's still fine, I can go to options etc, without lag. But when I disconnect from server and go back to default menu I got 4 fps back.

Oh, its only 4fps if you aren't in a map, okay. Well, then you are mostly fixed by the above cvar changes, I'll work on adding some UI around those options so less technical users can access them. I will also keep looking for way to speed up your out of map fps.

Thanks for help. At least I can play after I break through the menu and connect to server

Okay, next release will have a 'low video quality' check box in the Video tab of options. It will set the above options for you, and this mode also improves the rendering speed at the main menu.

@alfred-valve what exactly doing that 'low video quality' checkmark?

+1 i would also like to know EXACTLY what it does =)

It does the things discussed in this thread. So '-nofbo' on the command line, setting gl_ansio to 4 and gl_texturemode to GL_LINEAR_GL_NEAREST and also causing the big background picture to not be filtered as much.

To be clear, you could just manually do the above and get all the benefits except for the main menu change, the check box is just to help users that don't want to micro-manage their config.

i think that this GL_LINEAR_MIPMAP_NEAREST is default

GL_LINEAR_MIPMAP_LINEAR is the default now.

I'm not quite understand. If we activate the checkmark, from what value and to what value gl_texturemod will change?

If you check 'low video quality' then the texturemode is set to GL_LINEAR_MIPMAP_NEAREST.
If you do NOT have it checked, the default is GL_LINEAR_MIPMAP_LINEAR (which looks much better).

If I may add something yet - I get mentioned 4 fps in one other location and it's when I'm in game and then appears screen to choose my terrorist character or CT character (after I choose to be one or another team - that screen works fine btw). When it appears my fps drop down to 4, and after I click my character, they're getting back to normal.

if ur pc is intel check intel support
and download graphic accelerator

No it's not. I've posted my OS spec in first post.

I don't know if you guys from Valve are working on my problem or you just don't care.
Anyway I managed to find out something. I want to ask about files located at:

cstrikeresourcebackground

They are named '800_1_a_loading.tga' and so on.

I switched them to other ones but in form 1024_1_a_loading.tga etc. and also added to cstrikeresource BackgroundLayout.txt file with something like 'scaled' command.
And it works, menu works fine!

But only with that BackgroundLayout.txt file. Anyway - solution lies somewhere in resource folder.

So? It looks like I'm helping you to solve my own problem :|

Same problem here! . My graphics card is Nvidia Geforce FX 5200

Today have reinstalled CS and then got same problem with 4fps in menu. But if i switch video mode (Renderer) from OpenGL to Software -- menu start work normally.
Graphic Card GeForce FX5500. Driver update don't help. Steam reinstall w register cleaning same thing. Before reinstall everything was just perfect.
BTW Video tab in Options menu are changes, it was different before.

well, its a graphic problem if u use intel visit intel supportand download media graphic accelerator

Make sure you opt into the Half-Life and Counter-Strike beta (via the properties tab). If you still see the problem please run the game with '-dev' in the launch options and paste the output from the console after launching the game here.

@alfred-valve I can reproduce low (4-15) fps and a black bar on bottom of the screen when I run the game in 256 colors

8-bit also causes the problem

-dev output

I belive

is the problem.

In normal mode (32 or 16 bit) it's

Obviously, for some users, in some cases, the game decides to use 'GDI Generic' instead of primary GPU

And you're gonna laugh (or cry). snapshot also doesn't work in this weird setup. screenshot works 😆

Falling back to the Microsoft software renderer is also a problem, it will not render HL1 correctly without -nofbo mode.
I assume you are using the beta for all the above tests?

Sure.

And adding -nofbo doesn't fix falling to the GDI Generic. Same fps problem, same black bar on bottom of the screen.

8-bit, GDI Generic, 4-11fps. I can't reproduce it using 32 or 16 bit, but I assume, those people who have 4 fps in the menu and a black bar, they play in 32bit, but their system detects only GDI Generic renderer anyway.

however, everything is fine in -software mode. 100fps, no black bar

I downgraded and tested it again. 8-bit color depth.

Launch options: -dev -gl -sw -w 640 -h 480. Game fails to start with error
Works fine in software and D3D.

Launch options: -dev -gl -full -w 640 -h 480. Game ignores system color depth and forces 16-bit in-game.

Launch options: -dev -gl -full -w 640 -h 480 -32bpp. Game ignores system color depth and forces 32-bit in-game.

When I alt-tab, I see 8-bit desktop, when I alt-tab back, I see 32-bit in-game. In fullscreen everything works perfectly.

The beta update today should help here, it now better selections the OpenGL options that make sense to use.

It also prevents you running GL in 256-bit color mode, you need at least 16-bit support for GL, if you want lower color then run in software mode.

haha... you blocked every color mode below 16-bit. Now I can't check if the game is still falling back to the GDI Generic. After all, some players experience this issue running 32-bit. I hope you really fixed the problem.

Found a bug. If I run the game in 256 colors, the game fails to start and 'CrashInitializingVideoMode' registry key sets to 1
but the game still fails to start, even in 'software' mode. Vicious circle :)

Don't run in 256-bit color mode :) Calling this solved then.

Don't run in 256-bit color mode :) Calling this solved then.

Semantically speaking, it's 256-color mode, not 256-bit color mode; 256 color mode is 8 bits of color.

@m3x I saw that you solve your problem. I have the same problem with main menu. Can you upload your resource folder to see if it works for me too ?

@doTsw0w
https://www.dropbox.com/s/iii7k332e8xi10e/resource.rar

It only fixed my menu. You can try with other custom GUIs i.e. from cs-gui.com but only with resource folder.

Hey, today faced with this problem. CS worked fine couple days ago, and today 4 fps in menu and in game (OpenGL)
Reinstalled CS from scratch (removed all Half-Life or CS folders from steam), cleaned registry - doesn't help.
Tried -nofbo and GL_NEAREST_MIPMAP_NEAREST - doesn't help at all.
Software mode runs pretty fast, but quality rather bad.

p.s. W7 x64, i3 2120, 12Gb ram, GTX 760 2Gb. All drivers and DX are latest.

@eXpressionist Please open a new issue report as your issue is on radically newer, more capable hardware and this issue is closed.
