Dota 2 is a fun game but unlike it's older sibling dota 1 it has higher system requirements. The system requirements for dota 2 are:
Dota 2 Minimum System Requirements:
Spoiler:
Code:
* OS: Windows® 7 / Vista / Vista64 / XP
* Processor: Pentium 4 3.0GHz
* Memory: 1 GB for XP / 2GB for Vista
* Graphics: DirectX 9 compatible video card with 128 MB, Shader model 2.0. ATI X800, NVidia 6600 or better
* Hard Drive: At least 2.5 GB of free space

Spoiler:
Code:
* OS: Windows® 7 / Vista / Vista64 / XP
* Processor: Intel core 2 duo 2.4GHz
* Memory: 1 GB for XP / 2GB for Vista
* Graphics: DirectX 9 compatible video card with Shader model 3.0. NVidia 7600, ATI X1600 or better
* Hard Drive: At least 2.5 GB of free space
* Sound: DirectX 9.0c compatible sound cardI. Update your graphic card driver to the latest version
To find out your card go to Control Panel -> Device Manager -> Display Adapters. Then make sure you have the latest driver version. The links below will let you download the latest version for amd and nvidia.

The next step is to tweak dota 2 launch options, the options are available in Steam games library. Go to Steam games library, right click Dota 2 and select [Properties], then click on [Set Launch Options]..." like in the image below. There you can set parameters for dota 2 start.
The parameters recommended to set here are:
Code:
-console
-novid
-noaafonts
-high
-noforcemaccel -noforcemspd -useforcedmparms[-console] setting will enable the dota 2 console where you can type commands or see the log, [-novid] will disable the intro video, the creepy bald guy, [-noaafonts] will disable antialiasing of the fonts, [-high] will set the process priority of the game to high, [-noforcemaccel -noforcemspd -useforcedmparms] will disable the mouse acceleration in game.
We recommend you add all this parameters to launch options like this, then click on [Ok]: [-console -novid -noaafonts -high -noforcemaccel -noforcemspd -useforcedmparms]
III. Tweak Dota 2 in game video settings
Go to Dota 2 configuration by clicking
.
Then go to [Video]->[General]. Here first turn [VSYNC] off and then
set a lower [RESOLUTION], depending on the power of your computer. Start
low and test the game, then gradually increase until you are satisfied.
Next go to the [Advanced] tab and set everything off and low. You can try leaving [Textures] to medium.
IV. Configure Dota 2 advanced setting in config files
The following Dota 2 config will tweak the advanced dota 2 settings in order to maximize performance. In order to execute these setting each time your Dota 2 game starts you must put these command lines in the autoexec.cfg file. Go to:
Code:
X:\Program Files (x86)\Steam\steamapps\common\dota 2 beta\dota\cfg\In this folder you should see at least two files, config.cfg and video.txt. Here create a text file then save it as autoexec.cfg, be careful not to save it as autoexec.cfg.txt . After that you can open it with a text editor like notepad and copy the commands listed below. Each line in this file will be a command, anything after a `//' in a particular line is a comment and it's not executed.
dota2upc.cfg, copy this text in the autoexec.cfg file:
Code:
//dota2upc.cfg v1.0
//net_graph "1" // Draw the network usage graph
//cl_showfps "1" // Show current fps

display over X time
echo "---------------------------------------------"
echo " Dota2upc.cfg loaded successfully !!! "
echo "---------------------------------------------"
Code:
exec dota2upc.cfgV. Try advanced Dota 2 launch options
This final step is a little extreme and may cause crashes or visual glitches in the game. That's why it was saved for last. These are options for dota 2 launch, just like in step II.
The following launch option disables directx 9 external rendering, and will increase fps:
Code:
-nod3d9exThe following launch option allows you to set the dx level in which you want dota 2 to work:
Code:
// -dxlevel <option> Example:
-dxlevel 81
Code:
-dxlevel 80 - This DirectX level
provides excellent performance, and still retains shadows and
specularity (notice the shiny floors in the image). However, water is
still strictly opaque.
-dxlevel 81 - Exactly like DirectX 8.0, but water now has the option of being translucent.
-dxlevel 90 - The most commonly used DirectX level. Performance takes a
severe hit for a minimal gain in visual quality. Special effects include
enhanced explosions and increased texture depth in smoke grenades.
However, several glitches are present. Flash grenades can superimpose
your windows desktop icons on the screen, and specularity/bumpmapping
errors are common.
-dxlevel 95 - The same as DirectX 9.0, with the option of using High Dynamic Range lighting (HDR).The following option allows you to set a heap size for dota 2 process, memory usage.
Code:
// -heapsize <value> Example:
-heapsize 1572864
Code:
512MB RAM -heapsize 262144
768MB RAM -heapsize 327680
1024MB RAM -heapsize 524288
1536MB RAM -heapsize 786432
2048MB RAM -heapsize 1048576
3072MB RAM -heapsize 1572864
4096MB RAM -heapsize 2097152
