It's really not part of my plan to include a Nascar Racing 4 tweaking guide b'coz the game isn't as popular as the other 2 games I have here (Q3 and UT). Nascar owners know that the game's engine is slow and buggy right? It crashes/freezes, the GUI sometimes get corrupted, the game stutters and runs out of memory for textures and u find urself racing against the papyrus default cars b'coz the game didn't detect ur cards memory properly etc etc!

Well guess what?! I have juz the guide to fix those probs and more! That's what pushed me to create this tweaking guide. Enjoy!

**This guide will only tackle tweaking Nascar 4 in "OpenGL" mode.


This tweaking guide will always recommend two different settings depending on how desperate you are in gaining performance:

Level 1 - for systems who are near or slightly past the recommended system specs of PIII 500mhz, 128mb RAM, 32mb 3d card.

Level 2 - for systems who are near or at the minimum requirements of PII 266mhz, 64mb RAM, 12mb 3d card.

*Hit "F" while playing the game to enable the "fps gauge". The gauge should read 30 or more most of the time, but with Nascar 20-25fps still looks okay, u will hardly notice the game skipping.

=Configure 3d Graphics=

**Go to start>programs menu and head to Nascar "Configure 3d Graphics"

-Select "OpenGL" as ur renderer and click next
-For ur graphics mode:

Level 1: Select 1024x768x16
Level 2: Select 800x600x16 or 640x480 (if needed)
**I don't recommend using 32bit since the game doesn't look all that bad at 16bit.

-Do not put tick marks on both "run in a window" and "use software cursor".

=Graphics Tweaking=

**Run the game and go to the options menu

[Graphics Tab]

Car Detail:
Level 1: High (or Medium if u can't see the diff in quality)
Level 2: Medium

Left=High - Center=Medium - Right=Low

World Detail Level:
Read the "Player.ini" File Tweaking below

Drawing Distance:
Level 1: anywhere between 35-50
Level 2: 15 (if ur desperate) or 20-30

Left=High - Right=Low

-In mirror:
Level 1 and 2: I recommend a setting of 0 b'coz u only need to see the road and the cars behind u right? Displaying other objects like the walls, crowd etc is a waste of fps and is really useless.

Maximum Opponents Drawn:
Level 1: anywhere between 11-15
Level 2: 7 (if ur desperate for performance) or 8-10

-In mirror:
Level 1: anywhere between 4-5
Level 2: 1 (if u only care about the car nearest u) or 2-3

Mirror Objects:
Level 1 and 2: I recommend using only "medium" since having more detail on the cars reflection on the mirror is just a waste of fps and is at the same time useless.

Trackside Objects:
Level 1: All
Level 2: Some

Level 1 and 2: Enabled

Level 1: Enabled
Level 2: Disabled (enable if ur system can handle it)

-Shadows and Specular Highlights:
Level 1 and 2: I recommend that u disable them both since they will only pull ur fps down and it's really not a big loss in graphics quality. Its just a boxy looking shadow and some additional lighting effects anyway.

Level 1 and 2: Enable

-Dirt, Dust, Smoke and Skid Marks:
Level 1: Enable
Level 2: Enable (disable if ur having slowdowns when they show up on screen)

[Sound Tab]

Hardware Options:

-Driver and 3d Sound:
Level 1 and 2: I recommend using only "DirectSound" and 3d Sound disabled for better performance. But if u have a 3d sound card and performance doesn't get affected much by enabling its 3d capabilities, then enable 3d Sound and select whether ur card uses A3d or EAX.

Maximum Sounds Played:
Level 1 and 2: I recommend using only 8 for better performance

=Player.ini Tweaking=

**Go into ur Nascar 4 directory and open the players folder, open the next folder inside with ur name on it and open the "player.ini" file

[Graphic Options]

Level 1: anywhere between 45-60
Level 2: 65 (or higher)

**Note that the higher value u give this line, the better performance u'll get at the expense of lower 'track' detail. I HIGHLY recommend using 55 for best trade off between performance and 'world' graphics detail.
*This line is the same as the "World Detail Level" option inside the game. But adjusting it here will give u a more prescise setting.

*Exit and save changes

Left=High - Right=Low

=Core.ini Tweaking=

**Proceed inside ur Nascar directory and open Core.ini


Level 1: give it a value of 1
Level 2: give it a value of 0 to slightly increase performance. If u notice ur sound decreased in quality or have troubles after disabling it, just re-enable it again.

Level 1 and 2: give it a value of 0 (unless u enabled 3d sound inside the game)

*Exit and save changes

=RendOGL.ini Tweaking=

**Proceed to ur Nascar 4 directory and open RendOGL.ini

*This is where u can really give ur game a huge boost in terms of stability! The settings I'm going to give here will fix (it did work for me) the GUI corruption, game stutters, crashing/freezing, and the use of papyrus's default cars b'coz ur card ran out of memory for textures.

Level 1 and 2: Set this to 0

*Use the value which fits ur vidcards memory:

-64mb cards: 56623104 OR use Nascar's default value
-32mb cards: 30408704 OR 29360128
-16mb cards: 14680064 OR 13631488
-12mb cards: 11534336 OR 10485760

**Try the first value, and if ur still having probs, try the next one.

Level 1 and 2: 9985 (equivalent to bilinear <Set to 9987 for trilinear if ur system can handle it>)

Level 1 and 2: 9729 (bilinear <no trilinear option for this one>)

*Exit and save changes
